John Carpenter's Toxic Commando

Take control of a commando, team up with friends, and send the Sludge God and its horde of things-that-should-never-be back to the underworld. Choose a class that matches your playstyle, jump into your favorite ride, and use gunfire, grenades, special abilities, and katanas to save the planet.

In the near future, an experimental effort to harness the Earth's core ends in disaster with the release of the Sludge God. This eldritch abomination terraforms the area, turning soil into scum and living beings into undead monsters. Fortunately, the genius behind the experiment has a plan to set things right. He only needs a team of competent, highly trained mercenaries to finish the job. Unfortunately, they were all too expensive. That is why he hired The Toxic Commandos.
