The demo supports up to four player co-op online or two-player local split-screen. In the demo, players take on the role of four operatives and must protect mankind from Fuse, the nefarious alien energy source stolen by a paramilitary organization called Raven.
Fuse is the first multiplatform title from Insomniac Games, the studio most famous for its work on the Resistance franchise. It launches May 28 for Xbox 360 and PlayStation 3 and will not have an online pass or microtransactions.
The game was announced during the 2011 Electronic Entertainment Expo, when it was known as OverStrike.
