After a car accident knocks him unconscious, a man awakens from a coma, his face fully bandaged, to find that he has been admitted to a dilapidated sanitarium and that he cannot remember who he is or where he came from, or how he came to be there. He gradually remembers his first name, Max. As he delves into the asylum's corridors in search of answers, Max finds himself transported to various obscure and otherworldly locations: a town inhabited only by malformed children and overseen by a malevolent alien entity known as "Mother", a demented circus surrounded by an endless ocean and terrorized by a squid-like individual, an alien hive populated by cyborg insects, and an Aztec village devastated by the return of the god Quetzalcoatl. Max himself is often subsumed into a different identity in these locations, such as Sarah, his younger sister who died in childhood from a disease, and Grimwall, the four-armed Cylopsian hero of a favorite comic book. Between each episode, Max returns to the asylum grounds, blending real and unreal, each time closer to regaining his memory and unraveling the truth surrounding the mysterious Dr. Morgan, head of the asylum. He confronts his feelings of guilt surrounding the death of Sarah and his drive to save other children. Max remembers that he was working at the Mercy Foundation on a cure for the deadly DNAV virus, which primarily kills children, but Dr. Jacob Morgan, the head of the foundation and Max's med school colleague, cut funding and staff for his research. Morgan denied that Max was close to a cure and said resources were better spent perfecting the existing Hope drug, which slows the progress of DNAV but does not cure it, but Max accused him of favoring the Hope drug because it is more profitable. Max realizes that he is in a coma and everything he has experienced since the accident, including the episodes in the asylum, has been a product of his imagination. He uses Dr. Morgan as the focus of his frustrations, visualizing that Morgan has given him an injection which will kill him if he does not awaken and remove his intravenous line quickly. This allows Max to break out of the coma. He is happily reunited with his wife. Months later, Max's wife gives birth to their first child, and the Mercy Foundation publishes Max's cure for the DNAV virus. Morgan resigns from the Mercy Foundation and is prosecuted when it is discovered that Max's car was tampered with prior to his accident in an apparent effort to prevent the cure from being released. Max becomes the new head of the Mercy Foundation.

• Illustration — Dialog scene The game uses an isometric perspective and a non-tiled 2D navigational system. Each world and setting carries a distinct atmosphere that presents either the real world, the imaginary world, or a mix of both of the main protagonist. In many cases, it is unclear to the player if the world the character is currently in is real or a product of Max's own imagination. This indistinction underlines much of the horror portrayed in the game. The game is separated into different levels or "chapters" with each having a different style and atmosphere. The player must find clues, solve puzzles and interact with other characters to reach a final challenge, where the player must reach the end of a path while avoiding obstacles. Failure to do so (by, for instance, getting killed) causes the player to be transported back to the beginning of the path without losing progress, thus a game over in this game is non-existent. When the player reaches the end of the path, a cinematic is played and the game proceeds to the next chapter.

The game was published by ASC Games. ASC executive producer Travis Williams explained, "The whole point of this game is to freak you out, and it's actually the first one I've ever come across that really does it. And that's why I said, 'God, we've got to pick this one up.'"

The PC and iOS versions received favorable reviews according to the review aggregation website GameRankings. Next Generation said that the former version was "still vastly different and thoroughly entertaining. If only more companies would take gaming into as different a direction, our jobs would be a lot more interesting." The PC version was commercially successful. According to Mike Nicholson of DreamForge, the game sold roughly 300,000 units. Chris Kellner of DTP Entertainment, which handled the same PC version's German localization, reported its lifetime sales between 10,000 and 50,000 units in the region. According to PC Accelerator, the PC version was a "critical success" that helped to raise DreamForge Intertainment's profile as a company.

In 2013, a programmer from the Sanitarium development team announced a project on Kickstarter called Shades of Sanity that was touted as the spiritual successor to Sanitarium. The project failed to attain funding. In 2015, a Kickstarter-funded adventure game called Stasis was released by a South African independent studio, The Brotherhood. It has been compared to Sanitarium. On October 29, 2015, Dotemu released an iOS port of the game with touchscreen controls, dynamic hint system, achievements and automatic save system. In 2011, Adventure Gamers named the PC version the 36th-best adventure game ever released. On August 1, 2022, ScummVM added support for playing Sanitarium using the original Windows game files, enabling it to be played on the various platforms ScummVM itself supports. In August 2026, it was announced that a new version of Sanitarium would be released for Nintendo Switch, PlayStation 4, PlayStation 5, and Xbox Series consoles.
