Attention all crew members. Report to crew meeting at 0900 hours. This is a state of emergency. Repeat. This is a state of emergency.
In the void of space, loneliness and paranoia are commonplace. The Antioch is suspended above the planet known by researchers as Selecuia. The research mission on alien archaeobacteria and flora was your ticket to academic fame. But abruptly, the stations navigation and communication systems begun to fail as an unknown biomass started to form around the stations walls and computers. You've lost track of time. Has it been just weeks now? There was an initial pang of excitement, that perhaps the introduction of an unknown living substance would be just the discovery that brought fame knocking at your door.
You didn't know it was malicious, until bodies began turning up covered in the thick red paste of the biomass that is now so commonplace. Thick red spiderwebs of flesh hang from the ceilings and crawl along the doors. Trapped in the void of space, feeling like a fly caught in the web of a spider, your dreams of fame are just a distant light lost in the endless black that surrounds you.
Deaths are getting more common. One of the station cooks was found dead in the center of the crew quarters. His limbs were detached and nailed to the walls by fleshy red spikes and his eyes removed. Judging from the wounds, his eyes were bored through with a drill of some sort. The brutality is calculated. Something or someone intelligent is behind this.
Last night, you were called to a meeting of the crew. It has been agreed that a murderer, perhaps several, exist among the group of you. Moral fibers, transformed by the fear and loneliness of the void, have become moral wisps. It had been decided that one of the crew will be ejected into empty space each day. The deaths will stop by any means necessary and if the innocent aren't killed by the crew, the threat will reach them in due time.
You sleep with some confidence tonight. Hidden in your locker is a plasma rifle you managed to take out of storage before the biomass completely webbed the door shut. You're no space marine, but you're a decent shot. All that training killing rats with your dads plasma pistol back home might pay off.
You are the Station Researcher
You have no powers other than your vote at the crew meetings. Your only weapon is your wits. Keep a sharp eye out for strange behavior if you want to find those responsible for the terrible situation on the Antioch. You can hold up to two items and use up to one each night. You may also choose to give one of your items away or to dispose of it permanently.
You have the GM-PW22 Plasma Rifle!
The plasma rifle is charged with one shot. Once during the game, at night, you can shoot a player.
