As of late I've been playing some Alien/Aliens/AvP games and then realized that it would be brutal if my little Rimworld travelers landed on LV-426, built a colony called Hadley's Hope, and built a nice life.... Until around turn day 360.. Someone gets face ****ed and now is impregnated with an Xenomorph. Terror will soon arise as this is a colony with no military gear, and the Alien that will emerge is something fierce. Not Colonial Marines style, we are talking H.R. Gigers original Alien that is basically bullet proof to small arms.
At this point the alien grows and drags someone off to eggmorph them, and then begins this process with harvesting more colonists. The more people it drags off the more xenos will show up within three turns of each missing colonist. The Xenos would be able to pass through specific blocks and stuff to simulate jumping out of vents and shafts, ambushing quickly and even able to dispatch a crew of five within a few short seconds. Your colonials would need to research molotovs, flame thrower parts, and the weaponizing of engineering tools in order to fight back. Colonial Marines never show up. It's up to you to fight against the aliens and find a way to take out the nest. Around turn 500 W-Y Mercs show up and try to kidnap/kill colonists as well as Xenos for study.
