Swordquest: Fireworld is a game released for the Atari 2600. It was created as the second part of a four-game adventure series for that system that would, in turn, become part of a series of game playoffs hosted by Atari where successful players would be rewarded valuable prizes (in the case of Fireworld, a chalice made of gold and platinum, adorned with citrines, diamonds, green jade, pearls, rubies, and sapphires.). It was preceded by Earthworld and followed by Waterworld, which were released; the final part, Airworld, was worked on but never finished or released.
As told in the pack-in comic created by DC Comics, Torr and Tarr finally reach the chamber that holds the Sword of Ultimate Sorcery and the Talisman of Penultimate Truth, but before they could claim the sword, it falls into a hole and lands in Fireworld, a blazing inferno of caverns and creatures. The twins are now out to find the Chalice of Light, the only thing that can permanently quench their thirst in the place they're venturing in.
The player travels through various rooms, picking up and dropping off items and playing various mini-games in some rooms to access items stored in those rooms. If the correct items are placed in a room, a clue shows up, pointing the player to a page and panel in the comic book included with the game. There, the player would find a word that was hidden in that panel. The object is to find all five correct clues in the game.
In the final playoffs for this game, the chalice was awarded to Michael Rideout, who had kept it ever since in a safe deposit box.
