Entombed is an adventure action puzzle video game for the Commodore 64 developed and released by Ultimate Play The Game in 1984. It is the first sequel to The Staff of Karnath, and features the same aristocrat adventurer, Sir Arthur Pendragon, the second game in the Pendragon series.
The player controls Pendragon who has been trapped in an ancient Egyptian underground tomb. In typical Ultimate Play The Game style, the player walks from room to room in a flick-screen environment, trying to get out of the tomb.
