Sanatorium is a game based off slender and is part of the Slendermans shadow series. It has the same goal and gameplay of Slender. It takes place into a psychiatric asylum, hence the title. You have to collect 8 pages in order to escape from Slenderman. Unlke the original Slender, where you get inevitably caught by the antagonist after having collected the pages, yet possibly managing to survive waking up in the park unhurt in the light of morning, in Sanatorium, you have to reach the entrance, now accessible in order to escape. The difference is that the game explicitly states "you survived", whereas in the original, the nature of your victory is more uncertain and speculative, with no clear exposition on how Slender apparently spared you, or whether it all was a dream, leaving it to the player interpretation.
Their are two more Slender man shadow maps Hospice and Elemantary and 3 more coming in September.
