The Great Destroyer is a Co-op FPS action game, set on the planet Mars during the far flung future. You (and your buddy, if that option is chosen,) are a Space Marine, guarding a dig site on mars, that has recently unearthed an alien temple, of unknown origin. Despite first contact being many years ago, these ruins do not match any known race's architecture. Therefore, many Pirates, Swindlers and Robbers are trying to get into the temple and steal artifacts. Its your job to keep them out. What you don't expect, however, is your Commander, his Lieutenant, and a large number of your contingent, going rouge and occupying the structure. It is now up to you (and your buddy,) to infiltrate the temple, take down the Commander and Lieutenant, and stop them from disturbing whatever may lie within. As you (and your buddy) descend down, and progress through out the game, you pick up strange weapons, weird enhancements, fight loads of rebel troops, accidentally unleash the droid security system, and eventually, reach the core of the structure. There, you find the Commander and Lieutenant, standing in-front of a great beam of pure energy. Turns out, the Temple is in fact a giant super-weapon, able to obliterate all sentient species from any chosen planet. Can you (and your buddy) stop your comrades from activating The Great Destroyer?
