Insomniac’s newest game, Fuse, will have a demo available on PSN and XBL next week. The co-op demo will allow players to play four player online co-op or two player offline split-screen.

Fuse is a co-op shooter that features four characters with unique abilities and weapons. Solo campaign players will not be left in the cold with this game because of a feature called “LEAP” which will allow solo players to jump between the four characters at will.

Fuse will be Insomniac Games’ first multiplatform game as they have only released games for PlayStation consoles. Fuse will be out for PS3 and Xbox 360 on May 28th in North America and May 31st in Europe.
