33 Immortals casts players as damned souls staging a rebellion against divine judgment, and it does so at a scale almost no action-roguelike attempts: a single run hosts up to 33 players simultaneously. Developed by Thunder Lotus, the game drops participants directly into live raids through instant matchmaking, with no lobby setup required. A player can arrive alone or in a group of up to four friends and immediately join the larger force already fighting through the session.
Runs are structured as fast-paced raids built around horde combat and large boss encounters. Enemies, rewards, and encounter arrangements vary each run, and the weapons and relics players wield draw from themes of sins and virtues, each carrying distinct combat mechanics. Coordination happens entirely through in-game emotes, pings, and cooperative abilities rather than voice chat, and players can revive fallen allies mid-run. The design assumes chaos and builds around it: dozens of players combining effects and responding to the same threats at once is the intended state, not an edge case.
The game sits toward the demanding end of action-roguelikes in moment-to-moment combat pressure, though the perpetual presence of other players means a struggling solo contributor is rarely the single point of failure. Between runs, collected resources feed permanent upgrades to a player’s soul, broadening their available weapons, relics, and build options over time.
