X-Com: Enforcer

Action game where you play the Enforcer, a high-tech combat machine, fighting alien invaders in America in the early 21st century on city streets, rooftops, and in the sewers.

Earth’s top-secret extraterrestrial combat unit faces an alien invasion in America in the early 21st century. The mission is to eradicate the extraterrestrials.

A lone X-COM scientist has created the Enforcer, a high-tech fighting machine built from earthly robotics and scavenged alien technology. It is armed with high-powered weapons and sent into alien hot spots.

Combat takes place in battles on city streets, across rooftops, and in the sewers. The game uses the same engine as Unreal Tournament.
