Doom

A sci-fi FPS in which a space mercenary searches for his lost friend from the box art. Things aren't looking too good. You'll never navigate off the planet on your own. Plus, all the heavy weapons have been taken by the assault team leaving you with only a pistol. If you only could get your hands around a plasma rifle or even a shotgun you could take a few down on your way out. Whatever killed your buddies deserves a couple of pellets in the forehead. Securing your helmet, you exit the landing pod. Hopefully you can find more substantial firepower somewhere within the station. As you walk through the main entrance of the base, you hear animal-like growls echoing through the distant corridors. They know you're here. There's no turning back now.
