Sanitarium is a psychological horror point-and-click adventure video game that was originally released for Microsoft Windows.

[5] 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.

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.

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.

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.

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.

[23] 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.

The staff wrote that the game "came from out of nowhere to provide the creepiest, most compelling, and best-told story of the year, bar none".

[35] In 2015, a Kickstarter-funded adventure game called Stasis was released by a South African independent studio, The Brotherhood.
