Psychonauts

=== Setting ===
The story is set in the fictional Whispering Rock Psychic Summer Camp, a remote US government training facility under the guise of a children's summer camp. Centuries ago, the area was hit by a meteor made of Psitanium (a fictional mineral that can grant psychic powers or strengthen existing powers), creating a huge crater. The Psitanium affected the local wildlife, giving them limited psychic powers, such as bears with the ability to attack with telekinetic claws, cougars with pyrokinesis, and rats with confusion gas. The Native Americans of the area called Psitanium "whispering rock", which they used to build arrowheads.
When settlers began inhabiting the region, the psychoactive properties of the meteor slowly drove them insane. An asylum named Thorny Towers Home of the Disturbed was built to house the afflicted, but within fifteen years, the asylum had more residents than the town did and the founder Houston Thorny committed suicide by throwing himself from the asylum's tower. The government relocated the remaining inhabitants and flooded the crater to prevent further settlement, creating what is now Lake Oblongata. The asylum still stands, but has fallen into disrepair.
The government took advantage of the Psitanium deposit to set up a training camp for Psychonauts, a group of agents gifted with psychic abilities used to help defeat evil-doers. The training ground is disguised as a summer camp for young children, but in reality helps the children to hone their abilities and to train them to be Psychonauts themselves. Due to this, only those recruited by the Psychonauts are allowed into the camp.

Characters

The protagonist and playable character of the game is Razputin "Raz" Aquato (voice actor Richard Horvitz), the son of a family of circus performers, who runs away from the circus to become a Psychonaut, despite his father Augustus' wishes. His family is cursed to die in water, and a watery hand called the Hand of Galochio attempts to submerge Raz whenever he approaches any significantly deep water.
When at camp, Raz meets four of the Psychonauts that run the camp: the cool and calculating Sasha Nein (voice actor Stephen Stanton), the fun-loving Milla Vodello (voice actress Alexis Lezin), the regimental Agent/Coach Morceau Oleander (voice actor Nick Jameson), and the aged, Mark Twainesque Ford Cruller (voice actor David Kaye), said by Razputin to have been the greatest leader the Psychonauts ever had, until a past psychic duel shattered Ford's psyche and left him with dissociative identity disorder. Only when he is near the large concentration of Psitanium does his psyche come together enough to form his real personality, though he does appear throughout the camp in various roles (shopkeeper, boathouse manager, park ranger).
During his time at camp, Raz meets several of the other gifted children including Lili Zanotto (voice actress Nicki Rapp), the daughter of the Grand Head of the Psychonauts, who falls in love with him at first sight (which he eventually reciprocates); and Dogen Boole (voice actress Nika Futterman), the grandson of one of the Psychonaut's founders who can communicate with animals and goes around with a tin foil hat to prevent his abilities from causing anyone's head to explode.
Raz also meets the residents of the insane asylum including ex-dentist and brain surgeon Dr. Caligosto Loboto; as well as Boyd Cooper, a former security guard that holds a number of government conspiracy theories about a person known as "the Milkman"; Fred Bonaparte, an asylum orderly struggling control over his mind by a hallucination of his ancestor, Napoleon Bonaparte; Gloria Van Gouton, a former actress driven insane by a family tragedy; Edgar Teglee, a painter whose girlfriend cheated on him, leading him to have an obsession with bullfights; and Linda, the gigantic lungfish that, due to Oleander and Loboto's experiments on it (which included a mind-control chip in its brain) brings campers to the asylum.

Story

Razputin, having fled from his family's circus, tries to sneak into the camp, but is caught by the Psychonauts. They agree to let him stay until his parents arrive, but refuse to let him take part in any activities. However, they do allow him to take part in Morceau's "Basic Braining" course, which he easily passes. Impressed, Sasha invites Raz to take part in an experiment to determine the extent of his abilities.
During the experiment, Raz comes across a vision of Dr. Loboto, an insane ex-dentist, extracting Dogen's brain, but is unable to intervene. Raz eventually realizes that the vision is true after finding Dogen without his brain, but the Psychonauts refuse to believe him.
After receiving additional training from Milla, Raz learns that Dr. Loboto is working on behalf of Morceau, who intends to harvest the campers' brains to power an army of psychic death tanks. Lili is soon abducted as well, and with both Sasha and Milla missing, Raz takes it upon himself to infiltrate the abandoned Thorny Towers Home of the Disturbed insane asylum where she was taken. Ford gives him a piece of bacon which he can use to contact him at any time, and tasks him with retrieving the stolen brains so that he can return them to the campers.
Raz frees the mutated lungfish Linda from Morceau's control, and she takes him safely across the lake. At the asylum, Raz helps the inmates overcome their illnesses, and they help him access the upper levels of the asylum, where Loboto has set up his lab. He frees Lili and restores Sasha and Milla's minds, allowing them to confront Morceau. The inmates subsequently burn down the asylum, allowing Morceau to transfer his brain to a giant tank. Raz defeats him, but when he approaches the tank, it releases a cloud of sneezing powder, causing him to sneeze his brain out.
Raz uses his telekinesis to place his brain inside the tank, merging it with Morceau's. Inside, Raz discovers that Morceau's evil springs from his childhood fear of his father, who ran a butcher shop. At the same time, Raz's own father appears and the two fathers join forces. However, he turns out to be an imposter, with Raz's real father, Augustus, appearing and using his own psychic abilities to fix his son's tangled mind and beat the personal demons. At the camp's closing ceremony, Ford presents him with a uniform and welcomes him into the Psychonauts. Raz prepares to leave camp with his father, but word arrives that the Grand Head of the Psychonauts—Lili's father, Truman Zanotto—has been captured. Thus Raz and the Psychonauts fly off on their new mission.
