Bit Dungeon II is a high-octane roguelike adventure set in a grim world inhabited by the undead. Players embody a restless spirit aiming to reclaim the sanctity of a loved one's grave while exploring a sprawling overworld filled with randomly generated dungeons. The game emphasizes permadeath, compelling players to recover their soul post-mortem, while also offering a variety of weapons each with unique power attacks. As players progress, they can level up through weapon usage and confront formidable dungeon bosses, all enriched by an original soundtrack, with opportunities for endless character enhancement following completion.
