If you have been adventuring in Assassin’s Creed: Brotherhood, you will know it also comes packed with an absurd number of hidden items and collectibles that you need to find in order to achieve a certain Achievement/Trophy or get access to certain items in the game. Assassin’s Creed: Brotherhood “In Memoriam” Achievement/Trophy comes at a price of collecting all the Feathers in the game.

Once Ezio has been healed during his first mission in Rome, go west, and you will come across a small church near the border with Centro. Climb up to its roof and your first feather is there.
Campagna Feather #2
Go to Barracks where Bartolomeo lives. The second feather is on top of these barracks, on its tallest tower.
Campagna Feather #3
Once you unlock the eastern Campagna, go to Terme di Diocleziano, and you will come across the third and the last feather in Campagna. You cannot miss it!
