PlayStation All-Stars Battle Royale will let players beat the tar out of various Sony favorites on October 23, according to the PlayStation blog. Two more characters for the PlayStation 3 and PlayStation Vita franchise-mashing fighting game will also be revealed tonight at 6 p.m. PST at Sony's exhibition for EVO 2012.

　　A super smashing brawl for all brothers and sisters. The game's confirmed roster so far includes God of War's Kratos, Parappa the Rappa, Sly Cooper, Killzone's Colonel Radec, Twisted Metal's Sweet Tooth, the Fat Princess, Uncharted's Nathan Drake, and BioShock's Big Daddy. The new characters will bring the total to 10, though several official comments on the blog made it clear the selection will not end there. The game will also have several preorder-exclusive character costumes.

　　The game's melees will span several Sony-themed environments with static and interactive elements. Confirmed brawling locales include God of War's Hades, Ratchet & Clank's cityscape Metropolis, and Jak and Daxter's Sandover Village.

　　All-Stars Battle Royale will feature a number of single- and multiplayer game modes, as well as cross-platform online play complete with tournaments. For more on All-Stars Battle Royale, check out GameSpot's hands-on preview.
