Disciple of the Creed 30
Assassinate all your targets with a full DNA bar. (15) 
From Microsoft:

"Again, this achievement really only requires awareness and patience. You need to assassinate every target with a full DNA (health) bar, not just kill them in open combat. Make sure every assassination is a one-hit kill with your hidden blade. This doesn't mean that every assassination must be a low-profile hidden-blade attack though. Holding down for a hidden-blade strike for a high-profile assassination will still score this achievement."

-Link-

This achievement is currently glitchy. It has been confirmed that the above will get you the achievement, but less also will. Also, if you have every side mission done before you start the assassinations, it will unlock. For updates, check this -thread-
Eagle's Will 20
Defeat 100 opponents without dying. (12) 
As it says you must defeat 100 opponents without dying.

Tips:
  • Spend the majority of your time blocking.
  • Always try and counter kill them as it is a lot easier.
  • Run around the city killing every guard you see.

If you are having trouble, this glitch works for some reason:
At the start of the game in Masyaf, run along the far left side of the village until you see a spiked outcrop pointing up toward the mountain with a tree just in front. If you run into the corner at the point while moving left and right, you'll be able to wriggle up the cliff face. When you reach the top, jump off the edge of the map and you'll unlock the achievement!

Eagle's Flight 20
Last 10 minutes in open conflict. (16) 
This one is a lot easier than it sounds.
  • Attack a guard
  • If there is more than one, kill them until only one remains
  • Sit back holding block ()
Eagle's Prey 20
Assassinate 100 guards. (4) 
You need to assassinate 100 guards. It doesnt matter whether they are attacking you or not, but as a general rule, most of the time they will block you if they are aware of your intentions.
  • Press to equip your hidden blade, and press while next to a guard to assassinate them
Blade in the Crowd 30
Kill one of your main targets like a true assassin. (6) 
This has to be done on one of the main 9 targets.

To kill like a true assassin the tagret must not be aware that they are about to die.
  • Walk up to your target holding in low profile to blend.
  • When you're next to your target (still holding ), hold to assassinate your target
Tron Advice: It's easiest to do this on the first target.
Eagle's Challenge 20
Defeat 25 guards in a single fight. (10) 
A single fight means that your synchronization bar must remain red throughout the entire fight.

Attack a guard and hold block. Keep backing away around the town and gather a group of guards. The max I could get at once was 13. Once you've gathered the maximum (again 13 for me), kill them until one remains. Then gather another group and kill that twelve. I find it's safer to gather a third group and then kill them all. This makes sure you actually got 25 instead of 24.
  • Always keep one guard alive
  • Always keep synchronization bar at red
Eagle's Swiftness 20
Perform 100 Counter Kill in Fights. (2) 
You need to counter kill 100 opponents in fights. This doesnt need to be done in one go, but is specific to your game file.
  • Wait for your opponent to step towards you to begin his attack
  • Just before he hits you, press and you will counter him and kill him
  • Sometimes you won't kill him and just kick him away, this doesnt count towards the achievement.
Eagle's Dive 20
Perform 50 Combo Kills in Fights. (26) 
Combo kills are frustrating and take a lot of precision timing. Luckily you only need to get 50 of them this time.
  • While fighting, press to attack someone, the split second your sword makes contact with theirs, press again to combo kill them.
  • Constantly pressing until you kill them doesnt count as a combo kill
  • If you're having trouble with pulling off a combo kill, you can practice them in the courtyard in Masyaf
Eagle's Talon 15
Perform 50 stealth assassinations.  
A stealth assassination is an assassination without alerting the guard to your presence
  • This is best pulled off on guards on the rooftops and guarding doorways.
  • Press to equip your hidden blade, slowly walk up behind the guard and press to stealth assassinate them.
Eagle's Dance 10
Perform 50 leap of faith. (2) 
A leap of faith is when you jump from a high point into a stack of hay below. You perform one of these in the attack on Masyaf.
  • Hold , and forward to jump off into a stack of hay
  • You can do leaps of faith mainly off view points, but there are a few other locations.
  • Some locations require very little time to climb to the top again, meaning you can just repeat it off that point 50 times. A good example is in the west of Masyaf
The hands of a Thief 15
Pickpocket 200 throwing knives. (7) 
You may notice while walking around, some fat looking men wearing brown leather outfits with knives on their belt.
  • Target onto them with the and hold to pickpocket their knives.
  • This is easiest done later on in the game when your max amount of knives is at 15.
  • Just keep pickpocketing until you've stolen 200.
March of the Pious 5
Use Scholar blending 20 times. (3) 
Blend in and out of the same group of scholars 20 times.
  • Walk up to a group of scholars (a group of 4 guys in white robes), press to blend and again to blend out. Just follow the group and repeat 20 times.
Eagle's Eye 15
Kill 75 guards by throwing knives. (1) 
You need to kill 75 guards with throwing knives.
  • Stand far from the target
  • Press to select the throwing knives, Lock onto the target with the and press
  • If you run out of knives, steal some more
Enemy of the Poor 5
Grab and Throw 25 Harassers. (14) 
You will sometimes find a beggar run up to you and harass you for food, money etc.
  • Hold the and press to grab them. Once you've grabbed the beggars, throw them away.
  • The beggars must be different people
  • Sometimes you'll find a crazy person attacking you. Grabbing the attackers won't scare them and neither will it contribute to this achievement.
Gifted Escapist 5
Jump through 20 merchant stands. (7) 
Find a merchant stand and jump through the stand 20 times
  • Press , and forward to jump through the stand

NOTES:
  • For additional help with the Templars and flags, try this -thread-
  • For additional help with any part of the story, try this -thread-
  • For the Eagle achievements, the score is specific to the game save, so getting 25 leaps of faith in one save and 25 in another will not unlock the achievement. All 50 must be done in the same game save file.
  • When killing Robert de Sable, watch out for a glitch by the two archers that may cause you to fall into the floor. If you've fallen foul to this you will need to take your HDD to a mate's house and complete it there. Or it has been suggested to use a Lens cleaning Device.

Fly Swatter 5
Kick a Guard while using the Flying Machine. (8) 
This is on the mission where you fly the flying machine downriver after you have helped the thieves set the fires. You do not have to get this (not sure you can) when you test the machine for Leonardo for the very first time. Simply hold to lock onto a guard and kick them.

**Please note- this achievement is missable. You only get one mission in which to do this**
Messer Sandman 10
Stun 4 guards at once by throwing sand in their face. (16) 
For this achievement, you must go to the combat trainer in Monteriggioni, right in front of the Villa. Talk to him, look under Special Moves, and select Unarmed Combat. This training is for free, and will teach you how to throw sand. To do it, with only your fists and no weapons equipped, hold the button. When you let go, Ezio will throw sand into nearby enemies. It's best to do this on guards standing still, as it is difficult to pull off in combat.

You can also throw a smoke bomb, to stun the guards long enough for the sand to be ready. Once they come close enough, throw the sand at them.
Doctor 20
Perform an Air Assassination on a Poisoned NPC. (4) 
This can be done after taking the codex to you receive from Lorenzo to Leonardo in the mission "A Blade With Bite". First, try to find a patrol of guards, and an area with enough height to do a jumping assassination from. Wait until the guards get near the area, and then poison one of them. After that's done, climb up to whatever area you picked out, lock onto the poisoned guard (he'll be the one beginning to go crazy) and assassinate him.
No-hitter 20
Kill 10 enemies while remaining in conflict without being hit. (35) 
The easiest way to do this is to go to the San Marco district in Venice, with three smoke bombs. From there, attract the attention of the guards, and gather up enough for the achievement. Once you are surrounded, throw the smoke bomb, and begin assassinating them with your hidden blades. Once the smoke bomb wears off, throw another one, and repeat the process. Keep going until you eventually kill ten guards for the achievement.
Kleptomaniac 10
Pickpocket 1000 Florins. (5) 
This is another achievement that will come with time. It requires you to pickpocket 1000 Florins from the people. To pick-pocket someone, hold to begin walking fast. From here, just run into someone, and you will pickpocket them. The quickest way to do this is to pay a Herald 500 Florins to lower your notoriety level, and then immediately pickpocket him. This will get you your 500 Florins back. Repeat one more time to unlock the achievement.
Lightning Strike 10
Sprint for 100 meters. (7) 
With the amount of running you will be doing in this game, it's almost impossible not to unlock this achievement. Simply make sure that you hold + for the distances you run to count.
Sweeper 10
Sweep 5 guards at once by using a Long Weapon. (27) 
Like Messer Sandman, you must first go to the combat trainer in order to learn how to sweep enemies. It won't be free however, as it will cost 10000 Florins for the training in Long Weapons.

Once that's done, you must steal a long weapon from one of the heavy soldiers covered in armor. Once you get the weapon, hold , and let go when you have five guards nearby to sweep.
Venetian Gladiator 20
Discover the Assassin's Tomb inside Santa Maria della Visitazione.  
To find Assassin's Tombs, you must complete the mission "Novella's Secret". From there, you will gain the ability to find and visit all of the Assassin's Tombs. If you haven't filled your map out yet by synchronizing with the view points, the tombs will not show up on your map.

This tomb starts off with a chase, as you must follow a messenger and kill him. The end of the chase leads to a fight with all of the guards in the area. When this is done, it's time for some timed platforming. You must pull a lever, and then go around the area, grabbing onto other levers in order to unlock the main door. There are four levers in the area you must pull before the time limit is up.
I can see your house from here! 20
Discover the Assassin's Tomb inside the Torre Grossa.  
See Venetian Gladiator for more info. This tomb is over in Tuscany, and has just as much platforming as before. Now though, there are guards patrolling this area, so you will have to kill them as you go. The areas here are a lot more confined, so it's much easier to tell where you are going.
Hallowed be thy name 20
Discover the Assassin's Tomb inside the Basilica di San Marco. (2) 
See Venetian Gladiator for more info. This tomb is located in Venice, and is different from the other tombs you will go through. Instead of working your way towards the end of the end of the area, the game will put you smack dab in the middle of the building. You will have four switches you can step on, that drops a lever down that you must reach before the time runs out. Whenever you first step on a switch, watch the way the camera pans, as that is the path that you will have to take to reach the lever.
Prison Escape 20
Discover the Assassin's Tomb inside the Rocca di Ravaldino fortress.  
See Venetian Gladiator for more info. This tomb is located in a prison, so the corridors here are very tight. Like in Tuscany, there are guards patrolling here, but they aren't anything special. There are quite a few timed jumps here involving gates, so whenever you see a lever, you are going to have to be quick.
Choir Boy 20
Discover the Assassin's Tomb inside Santa Maria del Fiore (The Duomo). (1) 
See Venetian Gladiator for more info. Once you finish the mission "Novella's Secret", the icon will appear right on your map in Florence. Go there, and complete the mission for this achievement. This mission is very open as there are no levers or timed parts in this mission, you just have to climb and jump your way to the end. The entire area is open from the get go, so it can be easy to get lost if you aren't paying attention. If you get lost during all of the jumps, just try and look for the pigeons, they will show you where you have to go.
Assassin For Hire 10
Complete your first assassination mission for Lorenzo Il Magnifico.  
At the beginning of DNA Strand 5, you can start to do assassination missions, which are marked by the crosshairs on your map. Go to the area marked on the map, and accept the mission. There are several mission types to do, some of them telling you where exactly to go, and others require you to find the target on your own. Either way, upon completing a mission given to you, the achievement will unlock.
Macho Man 10
Defend a woman's honor. (3) 
This requires you to do the mission, "A Woman Scorned". When going back to your house after visiting your father in jail, look around for a fist icon on your map. It will lead you to a woman that will ask you to beat up her cheating husband. Once you accept, go over to where the husband is in your map, and just beat him up. He will be all alone, so the fight itself is very easy. Once he runs away from you, the achievement will unlock.
Steal Home 10
Win a race against thieves! (2) 
This is a fairly easy achievement to do. Races can easily be identified on your mini-map by the checkered patterns. There is a thief nearby where your father, Giovanni, is being imprisoned at. After you talk with the thief, you will have to beat his time. As long as you are quick with your jumps and climbing, and always sprint when possible, you can easily beat his time.
Show your Colors 10
Wear the Auditore cape in each city. (13) 
To unlock the Auditore cape, you must find and collect all 100 Feathers scattered throughout the game. Once you collect all of the feathers, go back to the Villa and put them in the chest in Maria's room. After the short scene, you must equip it. To equip it, pause the game, go to your inventory, and finally outfits. Go to the Auditore cape, and hit to equip it. From there, you must visit each of the cities in the game to unlock this achievement. You must also visit the mountain region in the game, where you escort Leonardo in the carriage.
Handy Man 10
Upgrade a building in the Stronghold. (1) 
At the beginning of DNA Sequence 4, you will gain the ability to renovate the city of Monteriggioni. You will be asked by the architect to choose which building you want to renovate. With the money you've gained, just choose any building you like, and the achievement will unlock. If you are short on money, the Tailor is the cheapest building to renovate, as it only requires 1000 Florins for the first renovation.
I like the view 10
Synchronize 10 View Points. (1) 
View points are the high areas in your map. They are marked by the eagle icons in your map, and always require you to climb up to them. Once you reach the top of the building that's marked, there is usually a short wooden beam that you can crouch on. From there, hit to synchronize with the view. Once that is done, a part of the map will become clear. Do this ten times over the course of the game for this achievement.
High Dive 10
Perform a Leap of Faith from the Top of Florence's Giotto's Campanile. (3) 
This can be done early on in the game. One of the first missions you will do as Ezio will have you go and beat up your sister's cheating boyfriend. The boyfriend just so happens to be right by this building, so once you finish the mission, it's just a matter of climbing all the way to the top of it, synchronizing with the view. Once you do the obligatory jump back to the ground, this achievement will unlock.
Mailman 10
Intercept a Borgia Courrier. (2) 
Every so often, while roaming some of the bigger cities, you will see someone free running, trying to get away from you. For this achievement, you must stop the courier, either by tackling him, or killing him. Try not to mix them up with thieves, or corrupt noblemen who you can kill to decrease your notoriety. Couriers can be identified by the red capes they wear, and are marked by the red on your map. Once you find one, they will be marked on your map, so it makes it much easier to find them. They aren't as fast as you are when it comes to running, but if you are having trouble catching up to one, use throwing knives. As long as they don't find a way to conceal themselves, you should usually be able to kill them outright. If they get far enough away from you though, they will disappear on your map, and you will have to wait for them to come again.
Tip of the Iceberg 10
Use your Eagle Vision to scan a Glyph in the environment. (1) 
This is an achievement in which you have to pay attention. All of the glyphs in this game are located near landmarks in the game that you eventually must visit. If you ever see a red eye on your map near a land mark, that means a glyph is there. To locate the glyph, you must go into Eagle Vision by holding the button, and you will notice it marked as a memory glitch of some sort. Once you find one, simply stand right next to it to start some dialogue and net the achievement.
A Piece of the Puzzle 10
Unlock a piece of Subject 16's video. (3)

From there, go and buy both colors to unlock the achievement. It will take 2300 Florins to dye your suit Ebony, and 150 Florins for Ivory.
In Memory of Petruccio 30
Collect all the Feathers. (48) 
These are the new collectibles for this game, you must find 100 feathers scattered throughout the entire game. As you gather more and more, you will be rewarded for collecting 50, and 100 feathers.

All the feathers you collect must be dropped off in your mother's room. You can check how many feathers there are in each city, and even each district. From the pause menu, go to DNA. After that, scroll all the way through until you reach the Feathers strand, and hit . From there, it will tell you how many feathers you have in each city. If you hit again on whatever city you want, it will tell you how many feathers you have. For Florence and Venice, it will actually tell you how many you have in each district.

There is a complete guide that has locations and pictures for all the feathers in the game. Look HERE for the guide.
Red Light Addict 10
Spend 5000 florins on Courtesans. (4)

From there, walk through the streets, and press . Every time you throw money, you will lose 10 florins. You must do this at least 30 times for the achievement.

If you are hard pressed for money, try pickpocketing people first. While you may not get much from most people, it's a steady source of income, and can make this achievement much easier.
Victory lies in preparation 10

Shrines are automatically shown on the map during Sequence 2, after completing a story related event. The shrine you must complete is part of the story (Terme di Traiano), and the rest will then show up as black wolf icon. Once you complete any given shrine, they will vanish from the map but can be replayed in the DNA menu. Also be on the lookout for 3 flags per shrine, since 18 of 101 flags are actually in the shrines and the map will not show them unless you see them in Eagle Vision first (but you'd be grabbing them in that instance). Below are the locations of the flags within each shrine.

Note: All shrines can be replayed by selecting them in the DNA Menu and going to Secret Locations. Terme di Traiano is the one exception. You can find this shrine by selecting it in Sequence 2.

Terme di Traiano
This shrine is associated with the "Golden Boy" achievement.

Flag 1: When you dive into the water and go through the only open gate, take a left.
Flag 2: You'll reach a gate/archway where you must use the broken piece of debris to climb over it. Instead of climbing over it, look left to see the flag. Jump back to the first piece of debris and jump to the wall to start making your way to the flag.
Flag 3: In the area with the balconies and pillars, it's on one of the pillars.

Basilica di San Pietro
This shrine is associated with the "Amen" achievement.

Flag 1: When you get to the top area where there are two doors leading outside to the rain, take the open area on your right. You'll see the flag which you must run up the wall and jump to the right.
Flag 2: As you chase you'll eventually start using lanterns to swing to different
platforms. Keep an eye to your left when you see two NPCs working on the building.
Flag 3: After defeating the Cardinal, go through the curtains, but don't leap. Instead, drop down to grab the last flag here.

Palazzo Laterano Shrine
This shrine is associated with the "One-Man Wrecking Crew" achievement.

Flag 1: Once you get to the second level area running along the beams, take a left when you have the option to go left or right.
Flag 2: You'll be in a room with a broken staircase and a statue. Climb the statue or wall climb and jump to get to the next flag.
Flag 3: For the last flag you'll drop down to the middle of some stairs. Look to your right to see where the flag is. Run up the wall and jump left to get across the gap to grab the flag.

Catacombe di Roma
This shrine is associated with the "Undertaker 2.0" achievement.

Flag 1: When you get to your first checkpoint (after climbing a ladder) look to the right in the big area to see the flag.
Flag 2: After you go down the big hole, you'll see a wall with a torch and some rings. Above is a gate with the flag behind it. Keep going, taking a right when given the option, then another right which eventually leads to the flag.
Flag 3: When you get to the chapel area (you'll see one of the wolf men), climb up and when you get to the poles, climb backwards to go higher to get a flag instead of going to the normal route.

Shrine in Il Colosseo
This shrine is associated with the "Gladiator" achievement.

Flag 1: The first flag is behind a prison gate in the first in the shrine. Go about your normal way up and just remember to jump over and drop down to get the flag before you leave the area.
Flag 2: You'll enter an area (after a chase) with a bunch of people. In this area when you get higher, you'll notice a red structure with red drapes. The flag is inside.
Flag 3: The last flag is very shortly after. You'll notice it moments after starting the horse chase. Either jump off and grab it quickly or dismount-jump (tap ) and mount on the new horse on the left.

Cloaca Maxima
This shrine is associated with the "Plumber" achievement.

Flag 1: After doing a small chase scene you'll end up facing 7 wolf men at once, then 4 more. In this area is the flag high up to the left of the direction the game wants you to go.
Flag 2: Continue on your normal path in the room with all the laundry. You'll get to the second floor area where more enemies will attack. The hallway they come from has the flag.
Flag 3: After fighting the leader jump into the water to the right of where you fought him, and dive under the gate to get the flag.

There are multiple buildings around Rome that can be renovated. These buildings can only be renovated once the Borgia tower has been destroyed in the area. Once its down, buildings can be renovated. Walk up to a un-renovated building, press and select the option of “Renovate.” The building will then be open for business and will increase your total revenue. Buy five and the achievement will unlock. Renovating any building in the Antico district will count toward the achievement.

The Antico district is the Southern-most district.

Tower Offense 20
Burn All Borgia Towers. (3) 

There are a total of 12 Borgia towers to burn down in Rome. To access these buildings, you must first kill the Borgia captain. If you happen to get caught while trying to kill the Borgia captain, he will flee. If you are unable to kill him before he flees, he will be gone until the next shift. Kill him when he appears again. You can use your Assassins to kill him rather easily. Upon killing the Borgia captain, the tower can be climbed and set ablaze.

You cannot access all 12 Borgia towers right at the start of the game. There are several locations in Rome that you cannot access. Upon completing Sequence 6, you will be able to locate the final Borgia Tower.

Show Off 20
Complete 10 Guild Challenges. (11) 

In each Guild, (Assassins, Thieves, Courtesans and Mercenaries) are several challenges that you can complete. These challenges can be viewed from the main DNA menu, as well as from each faction building. Some of these challenges can be completed by simply playing the game, however some are a bit harder to complete. Complete ANY 10 challenges and the achievement will unlock.

.. .- -- .- .-.. .. ...- . 20
Solve all of Subject 16’s Puzzles. (43) 

Subject 16’s puzzles can be found throughout Rome. Upon finding them, you’ll be transported into a separate world with a box. Walk up to the box and the puzzle will begin. Each puzzle can be replayed in the main menu beneath “DNA.” After the last puzzle is completed, the achievement will unlock.

If you need help on some puzzles, be sure to check out the Subject 16 Puzzle Guide.

Perfectionist 20
Earn 3 gold medals from the Animus Virtual Training Program (10) 

You will get a small tutorial of the Virtual Training Program when you first access it. The game will explain what it is, and after that point you can do it whenever you want by hitting . To earn this achievement, you must earn a gold medal on at least 3 different challenges (but they can all be in the same category). These categories are as follows:

  • Free Run
  • Stealth Assassination
  • Locate
  • Combat

The first 3 Free Run Challenges are the easiest to get gold in. Just run the courses to get the gold medals (probably attempting each a few times).

Brotherhood 20
Recruit 3 Assassins. (4) 

You will recruit 2 assassins as a part of the main story. Find one more, and the achievement will unlock. The assassins will show up on your mini map as a new icon which the game will introduce you to. Go there and kill the surrounding guards attacking the person (they look like a civilian). Once you have saved them they will join you. If you wait to long, they may be killed and you will have to move on to another (there are many on the map).

Welcome to the Brotherhood 20
Train a recruit up to the Rank of Assassin. (12) 

A recruit can be leveled up by sending them out on contracts. Do this by visiting a Pigeon Coop or an Assassin Tower. Check the icons (hitting ) on your map if you need to know what they look like. Once you have hit the top rank (rank 10) you must visit Ezio's hideout to hold the introductory ceremony. The achievement will unlock after the ceremony ends.

A contract is a mission you send your recruits out on to gain experience to level up, which gives them extra equipment as well as increases their stats. They range in difficulty and the game will show how high of a chance your assassin has to completing it successfully. It also has a timer on how long it will take. The best approach is to rank up with an extreme high percentage (involving multiple assassins if need be) and picking the lowest amount of time possible. The higher the rank and experience needed, the more dangerous jobs you will be sending them out on to benefit from higher rewards. For every assassin added to the contract, it will divide the experience equally. This is a way to power boost later on to rank up everyone quicker.

If an Assassin is killed while in battle, or killed while on a contract, the Assassin dies forever. He/she will be erased from your roster and you will have to replace them. In order to ensure your assassins are all safe and sound, never send them on suicide missions (ones that are low percentage of success). To raise the success level, have a few assassins go on one mission. With a larger roster of assassins, you'll be able to have a few groups out at once. You should be able to level a good amount of them up to the highest rank by the end of the story if you utilize it correctly.

Assassin Levels:

1: Recluta (0XP)
2: Servitore(10XP)
3: Assistente (30XP)
4: Milte (80XP)
5: Discepolo (180XP)
6: Mercenario (350XP)
7: Guerriero (600XP)
8: Veterano (1200XP)
9: Maestro (2000XP)
10: Assassino (3500XP)

Capture the Flag 30
Remove All Borgia Flags in Rome. (29) 

There are a total of 101 Borgia Flags in Rome. You can find them throughout Rome’s districts, as well as the hidden shrines throughout Rome (3 per shrine). You can track your progress of how many flags you’ve collected from the Main Menu. Go to Main Menu > DNA > Additional Memories > Flags. It is separated into districts, so you can track the flags easily. Although, you should never have to use this feature as there are maps you may purchase at an Art Dealer shop.

Obtaining these maps will make 83 of these flags extremely easy to find. There are 2 ways to get the maps to show up in the Art Dealers' shops. Option 1 is to find 25 flags. Option 2 is to complete the game. Do not go out of your way to follow guides to get the flags, as you will be getting maps for them anyways. The only ones you may need help on are the flags in the shrines. See the "Amen" achievement description for those specific 18 flags.


Location and Costs of Maps:

  • Centro District: 17,255 florins
  • Vaticano District: 16,788 florins
  • Antico District: 17,102 florins
  • Campagna District: 16,915 florins

This map shows you the location of all feathers in Rome. Use this to help you find the feathers with extreme ease. You may buy the map from any Art Dealer. The Feather Map costs 17,425 florins.

Dust to Dust 20
Find 1 Artifact in the Present. (26) 

*This achievement is missable*

After completing the final Memory sequence, you cannot access the present. Be sure that you exit the Animus at least once to find an artifact.

There are a total of 5 artifacts to be found in present-day Monteriggioni, but you only have to gain one for the achievement. Collecting the rest will offer no extra benefits. Pick any of the 5, or just follow the one chosen for the video.

  • Claudia’s Record Book- After exiting the Sanctuary, turn directly around, and its in the room off to the right.
  • Maria’s Feather Chest- After exiting the Sanctuary, head up to the top of the villa, and its in a hole in the roof.
  • Mario’s sword- Head south of the fighting ring, and head right. The sword is beneath a tree in a rock.
  • Ezio’s Belt- Upon picking up the sword, head straight down the alley and turn left. Head up the wall at the end of the alley, and the belt is in the corner.
  • Medici Cape- Head East along the main wall until you see the Church. Head inside, and the cape is inside.

Check out this video for the location of Maria's Feather Chest:

Serial Killer 20
Perform a Speed Kill Streak of 10. (18) 

You can do this in a few places where there are a lot of enemies. The best place to do it is in the Animus Training Program, where you can do it at your leisure. The best place is the Long Kill Streak challenge (last one on the list). Hold to start blocking when you have your weapon out. When a guard attacks you, press (while still holding ) right when the attack is about to hit you. This will cause you to counter and execute. Right as your execution is finishing up, press again highlighting any enemy nearby with the . Keep killing guards like this, keeping an eye out for an attack to counter sometimes by another guard. Explaining it makes it seem like a long process, but really it's all very quick. Watch the video if you'd like a better example on how it should look.

 

Spring Cleaning 10
Kill a guard with a broom. (25) 

At first you may not see any brooms until you advance through the story line. Just keep an open eye out while playing the game naturally until you see someone sweeping. They will be more frequent in the Centro District. To get the broom you can run into the person, grab and throw them, or even kill them to make them drop it. Pick the broom up and go to any guard and press to assassinate the guard.

Note: If you have the broom in your hand, you may still use the hidden gun. Using the gun (holding to initiate, letting go to fire) will not make you drop the broom. You may still obtain the achievement this way, even though you're technically getting the kill with the gun.

Your Wish is Granted 10
Throw money in a well (5) 

The first requirement is to have money. The currency in this game is Florins. You will no doubt be getting a lot of these in the game, but if you want to get it right away just steal money from the various people walking around by pressing near them.

Wells can be found throughout Rome. There is one just about in the middle of the map, on the far East side of Centro District. It's right in front of the gray building on the map, by the bank and the blacksmith. Wells will have a rope and bucket, with an outer octagon shape. There is wood around it as well, so if you find a hole and it doesn't look like this, it's not a well. To throw the money, hold and select the money bag icon. Now face the well and press and the achievement will unlock.

Fly Like an Eagle 10
Jump with the parachute off the top of Castel Sant' Angelo. (25) 

The parachute unlocks after all of Leonardos’s war machines have been destroyed. Meet up with him at the usual meeting place (the L icon), and you’ll have access to them. Once you have the parachute, climb to the top of Castel Sant’ Angelo (the top of the flagpole with a red flag) and jump off. This location is at the top of the map indicated by a circular shape. It is within a restricted area. The easiest way to get there is to wait until playing Sequence 8 Memory 2: "An Apple a Day". This mission is after a lengthy cutscene where a female is moaning and crying in a window. Look up and you'll see the flagpole you must climb. Get to the top of it and jump by pressing then press to open the parachute moments after jumping. If you die during this mission, you will spawn at the checkpoint near the window.

You may purchase parachutes by going to a tailor. To check if you have parachutes, press and select Inventory > Supplies > Parachutes. They cost 170 florins each.

Note: Sometimes the achievement won't trigger if you activate the parachute instantly after jumping. You should wait a moment before using it.

10
Win the highest bet at the Fights. (27) 

Fights can be participated in by going inside and beneath the Barracks. The Barracks will unlock after completing Sequence 3 and is in the Campagna District (icon is a white sword with a black background). Be sure to have plenty of florins in case you lose the bets. There are a total of five fights to partake in. After finishing the first four, set your bet to the highest amount (500 florins) and win. You must defeat a total of 5 mercenaries within 40 seconds.

There isn’t a real strategy here, besides spamming the button. Continue knocking mercenaries out, and you’ll earn 1150 florins. You can only use your fists, but you will still be able to do counter attacks which will save you lots of time.

Mailer Daemon 20
Access your email in 2012 (15) 

*Obtain this achievement as early as possible to avoid missing it*

At a certain point in the game, you’ll be told that you have new emails waiting for you. Exit the Animus, and head towards Altair’s statue. Press any button to access your computer and the achievement will unlock.

Be sure that you check your email before the final memory sequence. After completing the final memory sequence, you cannot exit the Animus (not even replaying DNA). If, for some reason, you do miss this achievement, don't be too stressed out. The email can be checked as early as sequence 2, so just start a new game on another save file if that happens.

Synchronization Established 10
Complete an entire Session with at least one kill (Multiplayer Only). (7) 

A session in multiplayer is any full game played. You must kill another player to gain this achievement. To kill someone, follow the indicator to your target and assassinate them (hitting ). You will most likely be targeted as well by someone else. Pressing to stun them does not count as a kill. You will be getting many kills while going for other achievements.

Note: This achievement can be earned in private matches.

Needle in a Haystack 5
Kill your target while hidden in a hay bale (Multiplayer Only). (27) 

Hay bale's are scattered within the various levels in multiplayer. Just move towards one to jump in, and don't move at all to stay. When an unsuspecting opponent is walking by, hit when indicated and you should get the achievement.

Note: This achievement can be boosted in private matches.

Strong Closer 20
Take the lead 10 seconds before the end of the session and go on to win (Multiplayer Only). (74) 

You cannot be in first place when there is 10 seconds remaining on the timer. It has to be the last 10 seconds of the game and not just the end of a round. When not in 1st place, take the lead in the last 10 seconds. This is hard to do legit, but with a high enough kill combo you may be able to get it with luck. Instead do it in a private match with a friend. Stay on the rooftops to avoid getting sucked into crowds thus earning blend points. You can do this with just 2 players in a Manhunt game.

Note: This achievement can be earned in private matches.

Fast Learner 25
Kill your target and escape your pursuer in less than 10 seconds (Multiplayer Only). (31) 

To get this, you must be playing a match where you have a target, as well being a target at the same time. You must kill your opponent and escape your pursuer within 10 seconds of the kill. Stunning your pursuer will give you an auto escape. The best way to lose someone is to run through the open gates that shut. You may get it playing normal, but this achievement can be boosted with a few friends in Alliance mode. Have your pursuer run around in circles while you have above your targets head. Make the kill and stun the pursuer (or run).

Note: This achievement can be earned in private matches.

Job skills 20
During Open Conflict, kill your target and escape (Multiplayer Only). (30) 

For this achievement you must have a minimum of 3 or more players (must have 1 as a target and 1 as a pursuer). Open Conflict is when a Target is aware of it's Pursuer. For this to work, your Target must be aware of you, and you must be aware of your Pursuer. Chase your target and kill them, then either run, hide, stun your pursuer, or have your pursuer kill a civilian. If boosting, just have all participants running around each other and then the one getting the achievement kill it's target, and stun it's opponent.

Note: This achievement can be earned in private matches.

Reach Level 50 (Multiplayer Only). (75) 

This one achievement is going to take a good amount of time, especially if you go for it legit. You may rank up in both Ranked and Player matches. The best boosting method is in the gametype Alliance. Alliance is not available right at the start, and requires a minimum level of 5 to play. Alliance requires a minimum of 6 players to start the game. The method is described below;

Mode:Alliance

Instructions:

There will be 3 teams of 2 people each. While boosting, always stay on the same team. The matches will last 2 rounds, and whichever team is boosting must boost for that entire round. They will be killing their targets and stunning their pursuers. Everyone must meet in a central area of the map, or a place that's easy to get to (usually somewhere like a big water fountain for example, or in front of big pillars). The team getting the points will be stunning the pursuers. It's best to switch targets each time you stun because the game will give a delay on the stunning if you keep stunning the same person. The targets must keep running into that area and let themselves be killed. You should take mental note and kill every other target that runs your way. Be fair and give your partner their fair share of kills. Below is an example of the roles.

Note: There are 2 rounds. The teams will be switching roles, so if someone was being stunned one round, the next they will be dying, etc.

Team 1: In this example Team 1 is the boosting team. They will never die, and will always do killing and stunning. The perks don't really matter for this team, but they will want to make sure they have a kill streak award set to give bonus points.

Team 2: This team is the targets. They will continue to run to the meeting place to get killed. A good idea is to have perks that allow faster running and climbing (certain perks are obtained at certain levels). This team will change to the pursuers in round 2.

Team 3: This team is the pursuers. They will be having a bit of a break during their round. All they have to do is get stunned, and sometimes maybe move a little bit if they wind up being far away from each other. This team will change to the targets in round 2. If anyone has the Resistance Perk (unlocked at level 27) it should be applied. This will let you get up faster after being stunned, and will really speed up the boosting.

Using this boosting method and depending on how organized your boosting party is, you can get on average around 30k to 40k or even higher per match. Each match takes 8 minutes (4 minute rounds). So you will get that experience once every half hour. Remember to always be fair during your boosting sessions and before it ends, make sure the last team has gone. Also, if you're going to leave the boosting sessions, alert the party you will be leaving so they can look for a replacement.

To find a boosting party, please use the Achievement Trading Thread.

Role Model 20
Get all the Co-op bonuses in 1 session (Multiplayer Only). (209) 

This is a very easy achievement but you will need at least 4 people to boost it. This is best done in an Manhunt private match. You will need to do the 3 stun related bonuses in one round, and the 3 kill related bonuses in the next round.

Stunning:

Co-Op Stun: Target the pursuer with  and have your team mate stun them.

Knock Out: Both you and your partner stun both of the pursuers at once (or within 10 seconds of each other).

Rescue: Have a pursuer get in a chase with your team mate (the pursuer runs around with the near your partner). Now stun that specific pursuer.

Killing:

Co-Op Kill: Press  on your target to lock on. Have your partner kill your target.

Multi Kill: Both you and your partner kill your targets at the same time (or within 10 seconds of each other).

Diversion: Have your partner get into a chase with a target (using to run around). Now kill that target without yourself being in the chase.

Overachiever 20
Score 750 points or more on a single kill (Multiplayer Only). (24) 

You must get a string of bonuses that equal 750 points or higher. You can do it in any way you want, as long as your bonus for that kill gives you the score. Look through the bonus menu and you can see which ones give what amount of points. You'll likely get this while boosting and it can all be done in a private match. Pick whatever combo of points will get you the achievement and do those. A good example is to kill someone while hidden (hay stack or blended) while in focus mode (when the has a full white circle around it).

Kill: 100 Points
Incognito: 300 Points
Hidden: 200 points
Focus: 150 Points
Total = 750 Points

You can boost this in private matches or you'll probably just get this randomly while playing in multiplayer. All types of bonuses count, even variety and kill streak bonuses that occur.

Abstergo Employee of the Month 20
Get every bonus at least once (Multiplayer Only). (358) 

This is one of the more difficult achievements in the game. You must get all bonuses in multiplayer at least once. All bonuses can be obtained in private matches except for the End Bonuses. For those it must be at least in player matches, but can still be boosted. For some of them you will have to play specific game types and have a minimum amount of players. There is no way to track of what bonuses you have completed. There are many bonuses to complete, so a separate guide for this achievement has been created.

Check out the Abstergo Employee of the Month Guide for more information.

NOTE:The Abstergo Employee of the Month achievement cannot be unlocked until you are at least level 29. This is because players cannot unlock the "Poison" ability until that level. There are two bonuses that require the Poison ability. These two bonuses are; Poison and Intercepted.

Ahead of the Curve 20
Perform a double or a triple escape (Multiplayer Only). (20) 

To do a double or triple escape, you must have 2 or 3 people pursuing you in Chase mode. To know if they are in Chase mode, they will have red (triangle-shaped) indicators above their heads. You can only get multiple people chasing you when you are doing extra well in the match. The game will try to balance things out and have you as the target to more opponents. The amount of pursuers is displayed on the top of the HUD where there are 3 triangles. The triangles that are lit up red are how many are after you. Having 2 or 3 people after you will not guarantee you get this achievement as you must escape them all at the same time, not just have two or more pursuers and escape from 1.

This is very easy to boost in private matches. Play a team game and have 1 person in the first group, and 2 in the second group. The pursuers must free-run around the map (using ) until both are in chase mode. Now have the sole person in group 1 either stun both, escape, or even have the two pursuers kill civilians.

Note: This achievement can be earned in private matches.

Clowning Around 30
Beat up the 5 thirsty harlequins. (37) 

Note: Sometimes they won't appear so run away and come back. Or use a Tunnel to travel away and then back. Also, if they die by some means other than your fists, do the same thing as above because they respawn.

You have to beat up (you must use your fists) five thirsty Harlequins. You will know if it counted because it says "X of 5 Harlequins beaten up." They are near the water, hence the thirsty part, so look along the river. Four are in Centro District and one is in Campagna District.

I. The First Harlequin is in Centro District North and a bit west beside the river. He is between the Highest Doctor symbol on the map and the second Highest Tunnel Entrance. He is on some stairs going into the water.

II. The Second Harlequin is in Centro District North West beside the river again. He is to the East of the Bridge that goes to Vanticao District. Starting from the beginning of the bridge, if you use your map and go along the river East you will see a shaded area with a lighter circle in the middle. Go North of that circle and you will see a set of double stairs. He is on those stairs.

III. The Third Harlequin is in Centro District West beside the river. Go to ROSA IN FIORE and go directly west from there. He is on a set of stairs again.

IV. The Fourth Harlequin is in Centro District South East under a bridge beside the river. Go to Ezio's Hideout and go DIRECTLY south of it. On your map you should see a Bridge that has lines going across it. He is under that bridge on the left side.

V. The Fifth and Last Harlequin is in Campagna District beside the Borgia Tower (Or Assassin's Tower) that is surrounded by water and cliffs. If you use your map and go West slightly from the Borgia/Assassin's Tower and then go slightly North, you will see a small rectangle that represents a small building. Go there and the Harlequin is behind the Small building along the edge of the cliff.

Special Delivery 20
Double Assassinate from a parachute. (10) 

Make sure you have some parachutes. More the better in case you mess up. Now find two or more guards standing still beside each other. Climb to the top of a building (high or low) and jump off the building. Press to use your parachute and glide towards the group of enemies. Once it says Assassinate in the top right corner, press . If you get two enemies, the achievement will unlock.

Grand Theft Dressage 20
Steal 5 horses from their riders, while remaining on horseback. (18) 

Note: This has to be done in consecutively without getting off a horse.

First call your horse or mount a random horse. Then you must find a Guard on another horse and press to assassinate him. You must repeat this four more times. If you get pulled off your horse or fall off somehow you have to start from the beginning. It is easier to find guards with horses in the Antico District.

Alternatively, the fastest way is probably to do the assassination mission Serf's Turf. You have six guards on horses right there. Start by the one who is alone when he is near the cliff as you won't get detected. Then go for the two together. Wait until the three guys are far and kill them both quickly.

You should now be undetected again. Now kill one of the three remaining. Both the others should become alerted. Just go close to one and assassinate. Be careful as one of the guards might get down off his horse and try to pull you down. Even if you have to replay the mission the starting point is really close.

Note: If you haven't done the Assassination Contract Serf's Turf, it is in the Campagna District North West. It is the one that is farthest up on the map in the first set you do.

Going Up 5
Kill a guard with the bag that drops from a lift. (14) 

Just find one of those lifts that you use to go up a building quickly. Once you find one, find a group of guards and get them after you. Once they are after you, run to the lift. Wait until a few are right underneath and then use the lift.

Easy Come, Easy Go 5
Pay 500 florins to an orator, then pickpocket him afterward. (23) 

You must first increase your Notoriety, so make sure you don't have the cape on that doesn't allow your Notoriety to go up. Once you have done that, find a Herald (use your map). Go up to him and Bribe him with (500 florins) and your Notoriety level will decrease. Once you have done that, hold to steal your money back from him.
