Gore: Ultimate Soldier (2002)

New technology has led to the development of an advanced combat training emulator, where the weak have died and the best become even better. Known as the Meat Machine, this device takes Marines where they have never been, shows them enemies they have never faced, and trains them with both existing and advanced weaponry. As one of a variety of characters, you'll explore expansive levels with many ladders and basements, pick up or destroy items, and conserve your ammo and stamina for intense firefights.
