Set in a world where a mysterious pit appears after a cataclysm, players descend into the dungeons of King Thosgar to defeat demonic minions. The game blends roguelike dungeon-crawling with arcade-style combat, borrowing elements from Xenon Valkyrie+ and Riddled Corpses EX. It supports single-player and local two-player co-op, featuring procedurally generated levels, permanent death, and a variety of weapons and abilities.
