Every person who has played a game in the Gears beta will receive a buddy token. Additional ways to obtain a token are by purchasing any Gears content off the Xbox Live Marketplace or by adding a 12-month Xbox Live Gold subscription to your account. Tokens can also be earned by having played 20 hours or more of the Gears 3 beta -- time already spent does count -- and by playing more than 100 hours of "any Gears of War title, lifetime to date."
Players have until May 4 (this Wednesday!) to complete the tasks and earn up to five tokens. Participants don't need to take any addition action for their tokens, and the alpha-numeric codes will be distributed by email starting May 8 (so make sure your account details are up to date). This will give players a week to team up with their buddies for some Gears 3 action before the beta ends on May 15.
