"Heretic II is a fantasy action-adventure game developed by Raven Software and published by Activision in 1998 continuing the story of Corvus, the main character from its predecessor, Heretic. Using a modified id Tech 2 engine, the game features a mix of a third-person camera with a first-person shooter's action, making for a new gaming experience at the time. This is the only Heretic/Hexen video game that is unrelated to id Software, apart from its role as engine licenser."
