The beta looks to show off a number of the game’s unique gameplay elements, including zip-lining, combat sliding, barrel bombs, psyche gas, and other things not typically found in your average Halo 3 match.
The multiplayer beta is invitation only, however, meaning you’re going to need to jump through a few hoops. Gamestop will be providing invitational code for PowerUp Rewards members, who will receive a code when they purchase a copy of Tom Clancy’s Ghost Recon: Future Solider.
If you don’t feel like buying Ghost Recon or giving GameStop any money, you’ll have another option: praying you win a code from Facebook. Ubisoft will be giving out five hundred beta codes Facebook to people who "Like" their page. Simply hit the Like button, cross your fingers and hope that you get an email notification once the beta launches. Otherwise you’ll just need to wait for the game to release on September 4, 2012.
