GameStop PowerUp Rewards members who pick up Ghost Recon: Future Soldier on May 22 at, well, GameStop, will receive a code to participate in a planned closed multiplayer beta for Far Cry 3, Ubisoft announced today. The beta will kick off this summer and last two weeks on the PS3 and Xbox 360.

If you don't want to buy Ghost Recon, Ubisoft will also be giving away 500 codes through Facebook. It sounds like this is going to be a pretty big beta, so best of luck to those looking for entry. Ubisoft will announce the specific window for Far Cry 3's closed beta at a later date.
