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