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

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, though his fellow inmates seem to know him simply as "Max". As he delves deeper into the asylum's corridors in search of answers, Max finds himself transported to various obscure and otherworldly locations: a small town inhabited only by malformed children and overseen by a malevolent alien entity known only as "Mother", a demented circus surrounded by an endless ocean and terrorized by a squid-like individual, an alien hive overrun by cyborg insects, and an Aztec village devastated by the return of the god Quetzalcoatl. 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 remembers the death of his younger sister Sarah years ago and the real reason behind his institutionalization.
