Ravenloft: Stone Prophet is a first-person 3D roleplaying game that uses an altered version of the 2nd Edition AD&D ruleset. It runs on the same DreamForge engine that SSI used for Ravenloft: Strahd's Possession and Menzoberranzan. Combat takes place in real time.
The game begins with two player-created characters sent to investigate a magical barrier, beyond which is a desert. What follows takes place in an Egyptian-inspired setting, rather than the Gothic horror motif that is more commonly associated with the Ravenloft campaign setting.
