There will be Cross-Play support, which will allow for battles between PlayStation Vita and PS3 players against their respective platform counterparts. It will all be about clashes, defeating the enemy and reigning supreme.
The PS Blog posted the exact features a shown below:
.You’ll be able to play as Kratos, Sweet Tooth, Colonel Radec, Sly Cooper, PaRappa and Fat Princess.
.You’ll be able to play in both the Metropolis and Hades stages.
.You’ll be able to try out four-player online tournaments and 2 vs 2 online tournaments. For the 2 vs 2 games we’ll be supporting friend invites, so you and a friend can fight another team online.
.This, of course, is only a tiny fraction of what PlayStation All-Stars has to offer, but we thought you’d love the chance to try it early and see what all the buzz is about. This beta is also really helpful for us as it allows us to load test the servers before releasing the game. Be sure to hop on quickly as we’ll be ending the beta on 30th October
