When you only have a few feathers left to find pause gameplay and go to the DNA strand. At the DNA strand there is a section at the end of the strand that shows you where the feathers are located. If you now go to the feather section it will show you in what districts the missing feathers can be found.
To do this equip the throwing knives and hold down RT + X while running off any roof. When you do this Ezio will continue running in a straight line off the roof in the air. To make him come down release the buttons or switch to another weapon. If you drop down you won't throw the knife but will waste ammo if you reach another roof, switching to another weapon will instead conserve your knives.
Perform a Leap of Faith from the top of the Giottos Campanile in Florence to unlock this achievement or trophy, worth 10 gamerpoints or a Bronze trophy.

Use the Throw Sand skill to stun four guards at once to unlock this achievement or trophy, worth 10 gamerpoints or a Bronze trophy.
The first step to unlocking this achievement/trophy is to learn the Throw Sand skill in the practice field in front of Villa Auditore in Monteriggioni. Speak to the highlighted trainer near the practice field and select Unarmed Combat under the Special Moves category. Practice the Throw Sand skill three times to add it to your arsenal.
To perform the Throw Sand skill, hold the X/Square button while unarmed and engaged in combat. Hit a guard with the sand and he will stagger on the spot for a few seconds.
To unlock this achievement/trophy you have to stun four guards at once. So, start by getting a sizeable group of guards after you. It might help to throw a Smoke Bomb down before throwing the sand. Though you cant use the Throw Sand skill while not engaged in combat, stunning the guards with a Smoke Bomb can give you some time to get some distance from the group so you can hit them with the sand as they approach.
Sweep five guards at once using a Long Weapon to unlock this achievement or trophy, worth 10 gamerpoints or a Bronze trophy.
The first step to unlocking this achievement/trophy is to learn the Sweep skill in the practice field in front of Villa Auditore in Monteriggioni. Speak to the highlighted trainer near the practice field and select Long Weapons under the Special Moves category. Youll need 10,000 florins. Practice the Sweep skill three times to add it to your arsenal.
To Sweep, you first need a Long Weapon (i.e., a Halberd or a Spear). Seekers carry Long Weapons.
Its best to hold off on this achievement/Trophy until you reach Venice in the main story, as Seekers are plentiful in the city. The best place to look for Seekers is near the Torre dellOrologio -- the restricted area in the San Marco district. Seekers are easy to find there, and there are plenty of guards to sweep as well. Once youve located a Seeker, assassinate him with your Hidden Blade and pick up his weapon by tapping the B/Circle button while standing over it.
Assassinating the Seeker will likely get some guards after you. Youll want to get a large number of guards chasing you before attempting to unlock the achievement. Dont Sprint, though, because Ezio will release his weapon if you do so. You can move more quickly by holding RT/R2.
Hold X/Square while engaged in combat (locked on a target) to Sweep with the Long Weapon. Keep holding the button until Ezio places the weapon behind his back to get the best coverage. With so many guards after you it can be hard to pull a Sweep off, as the guards tend to interrupt with attacks. Just keep trying, and provided you have enough guards after you, this achievement/trophy should come eventually. If the guards are too far apart, try running a bit ahead; the standard guards move at the same pace, so they tend to bunch up while in pursuit.
Hide five bodies in a single pile of hay to unlock this achievement or trophy, worth 10 gamerpoints or a Bronze trophy.
First, of course, youll need five corpses. Start by getting in a fight with a group of guards near a pile of hay. The quickest way to kill a group of guards is to throw down a Smoke Bomb to stun them; then you are free to go to town with the Hidden Blade.
To hide a corpse in a pile of hay, press the B/Circle button while standing over the corpse to pick it up, then approach the pile of hay and press the B/Circle button again to throw the body in.
Here are techniques that make the game easier with killing guards and making a quick getaway or a quick massacre.
1.Blood Mist-You need a smoke bomb for this 1st if your facing a large group of guards you equip your hidden blade then when they get close to you throw your smoke bomb down(the guards will aways be next to each other) so when their all around you use your double hidden blade and start taking down multiple guards in secends. Even if it's 10guards if you do this right with 2kills per blade then you should kill the group of guards b4 the mist/smoke dissipears and best of all your in it so people wont see you clearly and you wont gain much notority(or no notority at all sometimes)
2.Poison Mist-This is the exact same technique but you use the poison blade and only use it when theres 2or more brutes in the group of guards. Put down the smoke/mist (the group of guards will always atleast be weopon range together) so poison all of the brutes and they should start damaging the guards.
3.4way Hidden Blades- If you ever saw those houses with the door opened and a treasure inside instead of wasting money on distractions. 1st with your hidden blade take 2guards down on 1 side then b4 the other 2guards turn around take them out (make sure theres no passing guards or theyll catch you)
