Playstation All-Stars Battle Royale
Sony is slowly revealing details about All-Stars, and we got our hands on Nathan Drake and a Big Daddy in the game, as well as the Vita version.
The Big Daddy from BioShock is the slowest character among those playable in the demo, but he's punishing to anyone around him. When he fills his power meter at the bottom of the screen, three levels of super attacks are available in successive tiers. The first is a Little Sister he can release at a nearby enemy. The second is an area attack that kills everyone instantly, and the third is a giant flood that consumes the whole level.
Uncharted's Nathan Drake is much more nimble of a fighter, and his super attacks are a propane tank he can detonate, a concrete pillar he can topple (for a long-range attack), and a sarcophagus that unleashes a horde of zombies on the level (in that order).
SuperBot says it still has other details about the game that it hasn't revealed like the different multiplayer modes, single-player, and the complete roster of fighters. A hedgehog grenade from the Resistance series is one of the items you can pick up in levels, so it's a good bet that a character from the franchise will be among the final list.
I also played the Vita version of the game (which features cross-save and cross-play functionality with the PS3 version), and it plays just as well as the console edition. Super attacks can be initiated either by swiping the back touchscreen or by hitting L1 and R1 at the same time.
As good as the Vita version looks, the one criticism I have is that it can be a little hard to see the items you can pick up in the environment.
PlayStation All-Stars Battle Royale comes out for the PS3 and Vita this winter.
