Assassin’s Creed – Brotherhood: Unlock Bartolomeo’s Axe
In Assassin’s Creed: Brotherhood for the PS3, Xbox 360, and PC, you can unlock the Bartolomeo’s Axe for your character to use.
To unlock Bartolomeo’s Axe, you’ll need to get each guild in the game to level three. Once you do, it will be unlocked in Ezio’s Hideout.
