If you want to participate in Ubisoft’s PS3-only beta for the upcoming
Assassin’s Creed: Brotherhood, you had better head to your local Gamestop. The multiplayer beta of the upcoming game will kick off on September 13, 2010 for PS3 users. Access to the beta program will be granted with pre-orders through the retailer.
The beta is being offered in limited numbers and will be distributed on a first-come first-serve basis. Not everyone who pre-orders the game will be given a pass; once they run out, they are gone. Gamestop will begin distributing the passes for the beta on Monday, August 9, 2010 and will continue until they run out.
