Using a modified Quake II 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. While progressive, this was a controversial design decision among fans of the original game, a well-known first-person shooter built on the Doom engine. The music was composed by Kevin Schilder. Gerald Brom contributed conceptual work to characters and creatures for the game. This is the only "Heretic"/"Hexen" video game that is unrelated to id Software, apart from its role as engine licenser.
