Cell is a predominantly first person single player horror game with some elements of survival horror and roguelike games intertwined with it. It draws inspiration from games like Amnesia and Slender Man, and works by H.P. Lovecraft. It features puzzle-solving, hiding mechanics, some resource management, and traditional horror gameplay. It's set in 2017 inside an abandoned 1970s mental hospital (insane asylum) and you play as a 15-year-old guy equipped only with his cell phone. Using the various apps on their phone the player has to escape the asylum after being trapped inside by an evil little boy who haunts the building.
