John Carpenter's Toxic Commando

Take control of one of the commandos, team up with your friends and send the Sludge God and its horde of things-that-should-never-be back to the underworld. Choose the class that matches your playstyle, pile into your favorite ride, and unload an array of gunfire, grenades, special abilities, and freaking katanas as you save the planet.

L'histoire

In the near future, an experimental attempt to harness the power of the Earth’s core ends in a terrifying disaster: the release of the Sludge God. This eldritch abomination begins terraforming the area, turning soil to scum and the living to undead monsters. Luckily, the genius behind the experiment has a plan to make things right. All he needs is a team of competent, highly trained mercenaries to get the job done. … Unfortunately, they were all too expensive. Which is why he’s hired… The Toxic Commandos.
