Further Thoughts On Using 'Aliens' As Fodder For The Mutant Future Rpg System or Your Old School Post Apocalyptic Campaigns

Just the other night I was playing the Fallout video games with a friend and we were going through some of the 'special encounters' in the games. This reminded me of a series of posts that Chris Van Deelen has been doing on his D - Infinity blog for Mutant Future about the Aliens movie.
Because of the vary nature of the Xenomorph threat and their origins these monsters might easily show up in a derelict out the middle of the post apocalyptic wastelands quite easily in Mutant Future.

Chris has done a series of Colonial marine weapon conversions for the MF game including the ubigious pulse rifle, 88 Mod Four automatic side arm, and more.

I've run numerous games using the Alien species and by far the most successful have been those that use the first two movies, the original run of Dark Horse comics, and the mostly forgotten Aliens paper backs.
Colonial Space Marine ships crashed out in the wastes of Earth in Gamma World first and second edition. The artifacts of the Colonial Marines would routinely crop up for sail along with ammo in these campaigns.
Earth Hive allowed me to inject a whole other set of parameters into my old school campaigns. This book came out in 1992 and there have been major changes to the entire franchise of Aliens. But back in 1992 the wastelands and failed colonies of several worlds were infested with Xenomorphs.


Wiki has a good overview of the plot of Earth Hive bearing in mind that this entire book's plot line has been reconned into the 'official' universe: 

The book begins with a routine space junk cleanup mission in Earth orbit, with a small derelict spaceship being prepped for de-orbit and burnup. The crew doing the cleanup investigate the ship, and, much to their horror, an alien xenomorph stowaway on the derelict manages to board the cleanup crew's ship, and kill them. The ship is destroyed when one of the crewmembers panics and collides the cleanup ship with the derelict. However, everything was captured by the cleanup ship's black box.

A CIA-like organization, called the TIA, realizes the threat posed by the alien species, and is able to use the information in the black box to retrace the route of the derelict ship. A decision is made to send a Colonial Marine expedition to the origin planet of the derelict ship, presumably the home planet of the alien species. Wilks, a battle-hardened space marine, is picked for the job. He previously encountered the aliens on the colony world of Rim, where he managed to escape alive with only one survivor, a little girl named Billie. Wilks agrees to the mission, but first makes plans to break Billie out of a mental hospital, where she has been suffering from nightmares ever since her rescue from the aliens on Rim. On board the Colonial Marine ship is a marine named Mitch, with whom Billie begins a romantic relationship en route to the alien planet.

Meanwhile, greedy executives from the Weyland-Yutani corporation, learn of the Colonial Marine expedition to the alien homeworld, and make plans to intercept and destroy it. They hire a black-ops mercenary named Massey and his team of illegal combat synthetics, whose programming has been altered to permit the harming of human beings, in violation of theFirst law of robotics. It turns out that Weyland-Yutani already has a specimen of an alien on Earth, and wishes to keep its monopoly on the species, and prevent anyone else from obtaining a specimen.

A third group enters the fray, a religious cult that worships the alien xenomorph, and whose members believe that implantation by a facehugger alien is something akin to joining with god. After the marine expedition leaves for the alien planet, followed by the mercenary ship, the alien god cult manages to locate the Weyland-Yutani lab holding the alien samples, breaks into the lab using suicidal attacks, and manages to get several members implanted by alien facehuggers.

After arriving at the alien planet, the colonial marine ship is ambushed by Massey and the combat synthetics, assisted by the leader of the colonial marine force, who turns traitor for money. After seizing control of the marine's vessel, Massey kills the traitorous marine, leaving Wilks and the rest of the marines captive. The mercenary reveals his plan is to send the marines down to the planet, as 'bait' for the aliens, and then use the combat synthetics to collect the implanted marines. All of the marines except for Wilkes are sent down to the planet, unarmed, with the mercenary combat synthetics keeping a close watch.

On the planet below, the first team of Colonial Marines, including Mitch, is forced to enter an alien hive. Before the aliens can come out and attack, the mercenary synthetics who are keeping guard are attacked by another hostile alien species (not the xenomorphs). The Colonial Marines take advantage of this situation, and kill the mercenary synthetics and take their weapons.

During the surprise attack on the colonial marine vessel, Billie managed to hide and avoid detection in the initial sweep of the ship, and her name is not listed on the crew roster. She manages to kill one of the mercenary synthetics, get a weapon, and make her way to the bridge where Wilks and Massey are located. Billie and Wilks fight Massey, and manage to kill him. However, another group of marines is not so lucky, and is captured by a nearby alien hive. The surviving marines, led by Mitch, have no choice but to attempt a rescue. The rescue attempt comes at a great cost, only a few marines manage to make it out alive. Wilks and Billie fly down in a dropship to pick up the surviving marines, when Mitch is apparently killed by an alien - only to be revealed to be a synthetic as well. The Colonial Marine force included a team of synthetics so accurate, they could completely pass for human. Billie had no idea Mitch was synthetic, and is devastated.

Mitch and the rest of the marines make it into the dropship, just as a horde of aliens start to swarm over the ship and try to break in. The ship cannot take off, and Wilkes is about to undertake a suicide mission to try to go outside to clear the aliens off, when suddenly all of the aliens are killed. A new alien appears, looking something like a giant elephant. The characters in the book do not realize it, but this is the same species of creature whose crashed ship the crew of the Nostromo encountered on LV-426 in the original Alien movie - the so-called "Space Jockey." The elephant-alien does not appear hostile or particularly interested in the humans, as it returns to its spaceship without making contact with Wilkes. The remaining crew of the Colonial Marine expedition - Wilks, Billie, Mitch, a marine named Blake, and a naval crewman named Parks, return to their ship and head for Earth.

On Earth, the alien cult has successfully broken into the biowarfare lab containing the alien specimen, and has released wild aliens onto the planet. The aliens are slowly taking over, despite the best efforts of Earth defense forces. Over a period of several months, the aliens so completely dominate the planet, that most humans have been killed, and the rest have evacuated to earth orbit or other planets. As Wilks, Billie, Mitch, Blake, and Parks return to Earth, the last organized survivors of Earth are preparing to leave. Upon landing, a group of military survivors approach them, demanding that they hand over their ship. The encounter turns violent: Blake is killed and Parks panics and abandons the group. Wilks, Billie, and Mitch manage to stow away on a container ship headed for an unknown destination. They escape from Earth, with no idea of their final destination. This cliffhanger ending leads into the next book in the trilogy, Nightmare Asylum.

Most of the time using the Xenomorphs in the wasteland usually involves having the party encountering the horrors in some isolated valley with Space Jockey alien technology keeping the things isolated from the rest of the Wastes.
