Hellfire Warrior is a full-length Hi-Res adventure game that almost literally starts where Temple of Apshai, also by Automated Simulations, left off. It has no time limit, as do the shorter Morloc's Tower, Datestones of Ryn and Rescue at Rigel programs, but it have the same system commands and overall format as does the longer Temple of Apshai.

The game requires exploration of Levels Five through Eight of the Temple of Apshai. Your character explores the 60 rooms of each level in search of treasures and a sleeping Brunhilde. Naturally, a multitude of monsters are encountered and must be dealt with. The level number is proportional to the strength and power of its inhabitants, so if you're brand new to the Automated Simulations series, you might consider the Temple or, for the general flavor of the game system, the faster playing Morloc's Tower. On the other hand, if you liked the predecessors, you'll love Hellfire Warrior.
