The PlayStation All-Stars Battle Royale beta will kick off tomorrow on Vitaglobally.
PlayStation Plus members on PS3 will also be able to access the beta tomorrow in the US, and on Wednesday, October 17 in Europe, before it expands to everyone a week later.The beta will support Cross-Play, enabling Vita and PS3 players to fight with and against each other.
Here's the beta feature list, as posted on thePS Blog:

  • 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

Sony recently delayed the PlayStation All-Stars Battle Royale release date by one month to November 20 in the US (21 in Europe, 22 in Aus & NZ and 23 in UK & Ireland).
