EA and Insomniac have today officially announced Fuse, the story-driven, all-action 4-player co-op shooter formerly known as Overstrike, with a batch of fresh screenshots showing the game's elite, covert agents Dalton Brooks, Izzy Sinclair, Jacob Kimble and Naya Deveraux in action.

Brought together to fight a deadly alien energy source known as 'Fuse', the foursome have access to all manner of weird and wonderful technology powered by the eponymous volatile substance that will help them save mankind. Using Fuse's funky LEAP feature, you'll be able to switch between any of the four characters during combat, utilising their unique skills and weaponry.

“Fuse demonstrates what Insomniac does best: outlandish and gruesome weapons design, over-the-top action and a touch of humour,” said Insomniac Games’ Founder and CEO, Ted Price. “We’re especially excited to see how players utilise lethal teamwork by combining their Fuse weapons to stop a deadly arms race.”

You'll be able to play Fuse online and offline, levelling up your characters between modes with a unified game progression system. As you level up, you'll earn Fuse points and gain access to more powerful Fuse-driven abilities and experimental Fuse-powered weapons, making your team a force to be reckoned with.

Fuse will be releasing in March 2013. Check out all seven new screenshots below. There was supposed to be a debut trailer too, but that's sadly been delayed according to Insomniac's Ted Price. We'll have it for you as soon as it surfaces.
