Jaguar Doom story

The Story of Doom
Mars, and the gateways between its two moons, Phobos and Deimos, has been the side of inter-dimensional space travel testing. Recently, however, these passageways have become dangerously unstable. Experiments using human guinea pigs have met with tragic results. Something evil has been exiting the gateways.

As the only combat-read assault troops within 50 million miles of earth, you've been ordered, along with your buddies to Phobos. You arrive and are assigned to secure the perimeter of the base while the other marines go inside.

From outside the base you hear the carnage, guns firing, men screaming, bones cracking...then silence. Suddenly you're the last galactic marine alive, thrust into a bloody, gore-ridden underworld. Packing everything form chain saws to rocket launchers. It's up to you to annihilate Imps, Lost Souls, dead Marines, Barons of Hell...and ultimately avenge the brutal slaughter of your men.

Ending
ID Software salutes you!

The horrors of Hell could not kill you. Their most cunning traps were were no match for you. You have proven yourself the best of all!

Congratulations!
