Still Wakes the Deep is a psychological horror video game played from a first-person perspective. The game is set in December 1975, on an oil rig named Beira D in the North Sea. In the game, the player assumes control of a Glaswegian electrician named Cameron McLeary, who must navigate through the oil rig following a catastrophic event looking for a way to escape while surviving the harsh weather and evading the pursuit of creatures. The player character can run, jump, and climb ladders. However, the game does not have a combat system, and players must rely on stealth and solving light environmental puzzles to progress.
