Here's the debut trailer for Fuse  (formerly known as Overstrike), a four-player co-op action game being developed by Insomniac Games for the Xbox360 and PS3. Fuse is an alien energy source which has been stolen by an as yet unidentified clandestine organisation, and the Overstrike team have been deployed to retrieve it. The video introduces us briefly to the abilities of the four playable characters - Dalton's Magshield allows players to block and reflect projectiles back at enemies, Izzy's Shattergun enables you to immobilise and shatter opponents, with Jacob's Arcshot crossbow one can tag and incinerate enemies, and Naya's Warp Rifle fires off miniature black holes.
