The Keys of Acheron (1981) The first expansion pack to
Hellfire Warrior is
The Keys of Acheron by designer
Paul Reiche III. In it, the player attempts to recover four magical gems (the eponymous keys) for the wizard Abosandrus in order to prevent the immortal demon Kronus from invading the Earth. Kronus pursues the player through the four levels: "Abode of the Dragon", "The Temple in the Jungle", "The Crystal Caves", and "The Shadowland of Kronus."
Danger in Drindisti (1982) The second expansion pack for
Hellfire Warrior is
Danger in Drindisti by designer Rudy Kraft. In it, the player attempts to defeat four enemies of the wizard Yoturni, the Wizard King of Drindisti. Since a lack of room descriptions in level 6 and 8 are a restriction of the
Hellfire Warrior program, the dungeons were built around that fact and are suggested to be played out of order: "The Glass Wizard" (level 7), "The Abode of the Illusionist" (level 6), "The Temple of the Demonmaster" (level 9), and "The Realm of Mist" (level 8). ==References==
