Brain Slugs
Players control mutated brain slugs created through secret government experiments in the 1950s. Using psychic powers and mental illusions, the slugs move unseen, feed on human blood and electromagnetic energy, and manipulate objects around them. The game focuses on the slugs’ campaign against the agencies and scientists responsible for their creation, with players directing these faceless horrors as they spread and destroy.
