Dark Chambers

Dandy (later Dandy Dungeon) is a 1983 dungeon crawl maze video game developed by John Howard Palevich and published by the Atari Program Exchange for Atari 8-bit computers. It is one of the first video games with four-player, simultaneous cooperative play. Players equipped with bows and unlimited arrows fight through a maze containing monsters, monster spawners, keys, locked doors, food, and bombs in search of the exit leading to the next level. If a player dies, they can be revived by finding and shooting a heart. The game includes an editor for making new dungeons.
