If you didn’t pick up a specially marked copy of SOCOM: Special Forces, fear not. There is still time to get involved in the Resistance 3 multiplayer beta. By signing up to the newsletter of developer Insomniac Games you can get into the beta. The codes will be distributed at random before and throughout the public beta. It is important to note that if you make more than one application, all your applications will be void. Good luck!
The release of the public beta is currently not known, but prepare to continue resisting come September when Resistance 3 is released.
