During the Asian, more specifically Hong Kong, PSN update, a surprise item was put in the store; that item is the PlayStation All-Stars: Battle Royale Beta. For the time being, the beta is a PlayStation Plus exclusive for the Asian market. The beta features 6 characters – Radec, Kratos, Parappa, Fat Princess, Sly Cooper, and Sweet Tooth – and will focus on testing out the online multiplayer modes.
It is currently unknown whether other markets will get this beta as well but August does hold an “action-packed” Beta for the US PlayStation Plus users as stated by the PlayStation Blog. There’s a good chance that All-Stars is indeed that beta. For the time being, we’ll just have to wait.
