Mind Games

An organization book for Champions featuring the Parapsychological Studies Institute (PSI), a group of mutants who manipulate thoughts, erase memories, and bring nightmares to life. It details more than twenty PSI villains, including Institute members, students, agents, and support staff, along with guidance for using them against heroes or in an all-mentalist campaign. Several adventures draw heroes into PSI’s schemes, emphasizing mental powers and psychological conflict over physical combat. Compatible with Champions and other Hero System games.
