Sick of playing the Gears of War 3 against the unwashed masses? Microsoft and Epic Games have you covered, with a unique promotion that'll run during the final week of the game's multiplayer beta. On May 8, Microsoft will email every beta participant who's completed at least one match with a code they can use to invite a friend to join the fun.

According to Destructoid, additional codes will be made available to gamers who do any of the following, up to a maximum of five invite codes --
Buy Gears of War through Xbox Live's Games on Demand. Alternatively, buy any piece of Gears DLC or Gears avatar stuff.
Clock up over 20 hours in the Gears of War 3 beta.
Buy a 12-month Xbox Live Gold subscription.
Have over 100 hours clocked up on any Gears of War game to date.
You've got until May 4 to do this, and on May 8, as the final week of the beta begins, Microsoft will begin sending out invite codes.
