A deranged scientist is abducting students from the Psychonauts boot camp and a powerful new cadet named Raz stands alone against the lunatic. Raz must develop and unleash an arsenal of paranormal powers, including the ability to launch himself telepathically into someone else's mind - and take on their inner demons, nightmares and secret memories. Ultimately he must enter the mind of his worst enemy and destroy his dark plans at their source, while trying not to lose his sanity in the process.

Psychonauts thrusts players into a third-person psychic odyssey across thirteen incredibly unique levels: three set in the real world and 10 set inside the mental worlds of misfits, monsters and madmen. Once inside a mind, players can rise in rank by collecting figments of other people's imaginations; sort through their emotional baggage; clear out their mental cobwebs and crack open their memory vaults. As their rank rises, players are endowed with new psychic powers such as telekinesis, invisibility, pyrokinesis, clairvoyance and confusion.
