Battlefield 3's open multiplayer beta should now be available for all on Xbox 360, PS3 and PC. The infantry focused "Operation Metro" map is the sampler for the beta, pitting two sides against each other in Rush Mode. One team defends, while the other attempts to destroy several sets of objectives before they get turned to Swiss cheese.

The beta will end on October 10. There's not much time to fret afterward, as the full game will hit stores and EA's Origin shop on October 25.
