If you’ve always wondered who would win in a fight between Sweet Tooth and Fat Princess, then you might not have to wait much longer to find out. The eagle-eyed editors over at IGN have discovered that SuperBot Entertainment has kicked off a top-secret beta for upcoming PS3 mascot mash-up, PlayStation All-Stars Battle Royale.

The private beta – which appears to be invite only at the moment – is limited to two active periods: 12:00PM PT on 27th July until 23:59PM PT on 28th July, and 12:00PM PT on 3rd August until 23:59PM PT on 4th August. However, users are reporting that the beta is live now – so it’s unclear whether the test will stay online between the two allotted phases.

Strangely, PlayStation Plus members in Hong Kong also currently have access to the multiplayer test, which includes Sweet Tooth, Radec, Fat Princess, Sly Cooper, Kratos and PaRappa the Rapper. Hopefully, the beta goes public pretty soon.
