A free action-horror game in the spirit of Lethal Company and Among Us. The game pits three players against one. The latter, in the role of a stalker monster, pursues the crew throughout the laboratory, relying on sound and terrain features. He can also influence victims with psionic powers, destroy escape routes, and destroy exit doors. The players themselves need to develop an escape plan and slip past the monster unnoticed to get to the exit from the laboratory.
