Playstation All Stars: Battle Royale has just premiered a whole bunch of gameplay footage. During the conference They showed off a battle between 4 individuals: two using the playstation 3, and two using the PS Vita. Yes thats right, the Vita. This can only happen by Playstation All Stars: Battle Royale being cross-platform.
The game will be launching sometime this holiday season and looks to be a great place-holder before the rumored sequel in the Smash Bros. series.
