The game was announced with a very spooky first-person cinematic trailer, which featured a bunch of moments of psychological horror as well as a menacing sanatorium. The sanatorium actually seemed to be the same one that appeared in Until Dawn. So perhaps--this is purely speculation right now--they're in the same universe?
There was no word on the release date for the game, but The Inpatient is in the works for PS4. Supermassive also announced a shooter called Bravo Team.
