A run n'gun budget game in which you must destroy the aliens invading a base and collect the four parts of the secret weapon you need to destroy the alien queen. The back of the box says:
"Seriously destructive combat action. The Alien queen and her breeders must die. If you fail her legions will swarm across this system bringing a wave of death and destruction in their wake.
As one of our most experienced combat marines, you have been selected for this very dangerous mission. You've been issued with an extremely powerful plasma blaster and impact grenades. Your main objective: Destroy the alien base.
WAR MACHINE features legions of technomilitary adversaries, evil bio-mechanoid blood suckers and armour stripping acid baths."
