If you're a member of 360voice.com you can sign up here for the community game night that will render you a badge and the possibility of winning t-shirts from Infinity Ward and the chance to play along side a member of the Infinity Ward staff.

For more information, go here. I signed up for Friday night but from my understanding as long as you sign in to live and play on those given days you are eligible to win prizes for just playing CoD4, single or multiplayer.
