Assassin's Creed II

You can unlock this as early as DNA Sequence 11. Following the memory ‘Petruccio’s Secret’ in DNA Sequence 1, you are able to start gathering feathers, one of the collectibles in this game.

There are 100 feathers dispersed throughout the five cities. Some are in plain sight and some are hidden, but they are really not difficult to obtain. Using your Eagle Vision (hold ) allows you to see the feathers better as they glow white like treasure chests and glyphs. Once you’ve collected your 100th feather, the achievement will unlock.

Number of feathers in each city:
- Florence – 27
- Monteriggioni – 4
- Tuscany/San Gimignano – 11
- Romagna/Forli – 12
- Venice – 46

To see how many feathers you’ve gathered in each city, pause the game and select ‘DNA’. From there, use to move down the strand until you reach ‘Feathers’. Press to further open that strand. Move through the different cities to see how many feathers you’ve collected in each. For Florence and Venice, press again and it will break down how many feathers you have collected in each district. Unfortunately, there is no in-game map of the feather locations.
