Playstation All-Stars: Battle Royale, the PS3-Vita multiplayer, multi-star brawler, is currently in closed beta, but could head into an open beta closer to its October release date.
Chan Park from developer SuperBot Entertainment posted on the Playstation Blog, “While [the beta is open to] just a small group now, in the coming weeks we will continue to send out batches of codes as we gradually expand the beta; so keep your eyes open. You just might receive an invitation to join! Keep checking back with the blog for more information around the public beta, starting with early access to PlayStation Plus members.”
From the looks of it, the beta will go public soon, with Playstation Plus subscribers getting first dibs.
Playstation All-Stars: Battle Royale is scheduled for release on PS3 and PS Vita on 24th October, 2012.
