Two things we're quite sure of regarding Ms Splosion Man, the next game from Twisted Pixel and semi-sequel to Xbox Live Arcade game 'Splosion Man: it is coming to Xbox 360 this Wednesday, July 6 for 800 Microsoft Points.
That's straight from the developer's press release on the matter.
The other thing we're not so sure of (yet). But Rock Paper Shotgun spotted a Steam listing, since removed, for Ms Splosion Man, potentially a clue that the game is not merely an Xbox Live Arcade title, but a future PC release as well.
Twisted Pixel released The Maw on PC in 2009, but its most recent efforts - 'Splosion Man, Comic Jumper and the forthcoming Kinect shooter The Gunstringer - have been Xbox 360-only jams.
