Dark Chambers is a top-down dungeon crawling game that was developed by Atari for the Atari 2600 and the Atari 7800. It is a reworked version of Dandy, which was heavily influenced by Dungeons & Dragons and features much of the same gameplay. With one or two players, the objective is to get through a dungeon filled with gradually escalating monsters floor-by-floor. While the only weapon that can be used is a bow and arrow that only shoots one arrow at a time, the player can pick up special items to ease the journey, such as swords that increase power and bombs that kill all enemies on the screen.
aiqiyou and hellagels both play in 2-player mode on the Advanced difficulty for this run and get through all 26 floors as fast as possible, manipulating RNG as much as needed for certain randomized levels to output the most optimal maps and influence the monster AI.
