In their press conference today, Sony detailed the way players will be able to compete with their favorite PlayStation characters on both the Vita and the PS3.
Nathan Drake and Bioshock's Big Daddy were confirmed to join the cast and an on-stage demo showed two players playing on PS3 and two players competing on separate Vitas. PlayStation All-Stars Battle Royale will support cross-saves in addition to cross-play.
It's not yet known if purchasers of one version will receive the other in the package or if separate purchases are required.
