The ship came in for a hot landing, which is not too unusual in these parts. What was unusual were the bullet holes and other signs of barely escaped combat. And then the fire started, and with the smoke and the screams it was hard to tell who was who. Not that it mattered much, in the end. To be honest, Im not even sure who I am anymore. I dont intend to stick around long enough to find out.

Under the Skinis a one-shot adventure for theMothershipsci-fi horror RPG system. Affectionately inspired by the 1982 cult classic filmThe Thing, it presents an urgent mission with a hideous twist: any character, including the PCs, may be the monster in disguise without even realizing it themselves. Have some replacement character sheets ready, because life is cheap and trust is costly out here on The Rim.

Keep your eyes open for:

• The labyrinthine outpost of Rizzos Rest,soon to be nothing more than corpses and ash.

• The flesh-molding Monster,who preys on isolated victims and split parties.

• 8 NPCs with fully-detailed character sheetsto be used as replacement PCs once they start dying.

• ThePelican,a dilapidated shuttle that might be the only exit off this doomed planet — and the entry to a life as interstellar outlaws.

• The OMEN System,a method to secretly track who the Monster is and how likely it is to be a unwitting Player Character.

• Helmut,Rizzos Rests unofficial guard dog. Unflaggingly loyal, beloved by all, andveryeager to investigate strange sounds echoing in the darkness.

• And more!
