This is an adventure for Mothership Role Playing Game. You will need the base game to play.

A quiet life dashed as the crew of a middle-of-nowhere pitstop are caught in-between two groups of distraught and paranoid survivors, each carrying their own secrets. 

A forest fire trapping all within the outpost, the only escape a small battered ship. Smoke, distrust, and impending violence billows through the the air. 

Amidst the tension, something stalks, kills and replaces. A perfect mimic, but under its skin...

A one-shot adventure inspired by the 1982 cult classic film The Thing, where even players may be the monster without realizing. A host of paranoid and suspicous NPCs both serve as suspects and replacement PCs should a player be taken or be revealed to have been replaced.
