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