Series	X-COM

The game is set during the First Alien War in 1999. Unmentioned in the storyline as played out by X-COM: UFO Defense, funding was being provided to a program tasked with creating the ultimate robot warrior, led by a Professor Able Standard. However, owing to funding cuts by nations involved with the X-Com program, they were forced to abandon the project.

Professor Standard refused to stop the project, carrying it on in secret in the Nevada desert. On completion, Enforcer was unleashed on the invading alien hordes. [1]

Although set during the first alien war, the story portrayed in the game is not reflective of the canon of the game series as set out by the first four X-Com games and therefore takes place in an alternate timeline. During the end the scientist discovers an alien mothership is about to unleash an attack on Earth, and only Enforcer can stop it. Eventually this leads to a showdown with a cloaked female "High Ethereal" who taunts the Enforcer, and after the Ethereal is defeated the Mothership self-destructs and Enforcer is jettisoned into space, with the scientist's dying words echoing through its mind before fading to black.
