If you want first dibs on the multiplayer beta of Gears of War 3, you'll need to pick up Bulletstorm on February 22.  But not just any copy of Bulletstorm, you'll need to get the Epic Edition.  According to Computerandvideogames.com, those who pick up the Xbox 360 special edition will get "early access" to the multiplayer beta.  PlayStation 3 owners will get nothing, and like it.  (I'm just kidding.)
