33 Immortals is a large-scale cooperative action roguelike inspired by Dante's Divine Comedy, dropping up to 33 players together into hellish, ever-changing arenas to battle hordes of enemies and towering bosses shoulder to shoulder with strangers or friends.

Each run lets players build unique combinations of weapons and abilities as the fight escalates, blending roguelike progression with the chaos of mass-scale multiplayer combat. Its scale and afterlife setting give it a distinct identity among cooperative action games.
