Nightmare of Druaga: Fushigino Dungeon is a roguelike dungeon crawler RPG for the Sony PS2. The game weaves its story around the classic character Gilgamesh as he ventures through the treacherous labyrinths beneath the Tower of Druaga. Players explore procedurally generated dungeons, engaging in turn-based combat and collecting loot. The game combines tactical strategy with randomized levels, where death is permanent, forcing players to restart with each new attempt, embodying the brutal difficulty typical of the Mystery Dungeon series.
