33 Immortals leaves Early Access tomorrow, June 10, giving Thunder Lotus' enormous co-op roguelike its 1.0 launch after more than a year of public testing on Xbox and the Epic Games Store.
The studio says 33 Immortals will launch at 11am EDT on Steam and reach version 1.0 on Epic Games Store and Xbox. The Steam listing confirms Thunder Lotus as developer, with Thunder Lotus and Kepler Ghost listed as publishers, and describes the game as a 33-player co-op action roguelike built around instant matchmaking, boss fights, permanent upgrades and large-scale runs.
That makes tomorrow more than a routine date change. 33 Immortals has been playable for a while, but 1.0 is the moment when its unusual pitch has to stand on its own: can a roguelike raid work with 33 strangers, fast sessions and no mandatory voice chat?
A roguelike trying to bottle the MMO raid
33 Immortals is easy to describe and harder to make convincing. Players control damned souls rebelling against God's final judgment, then jump into top-down action runs where dozens of allies carve through monsters and bosses at once. It borrows the shape of an MMO raid, strips away the calendar planning and asks instant matchmaking to do the social heavy lifting.
On the Steam page, Thunder Lotus says players can drop in solo or party up with up to four friends. Coordination happens through emotes, pings, shared objectives, revives and cooperative abilities, not through a guild night or a voice channel full of people calling mechanics. That is the part worth watching. Plenty of games promise cooperative chaos. Fewer try to make raid-scale teamwork readable in sessions closer to an action roguelike.
The run structure is familiar in the right places. Players collect resources, unlock permanent upgrades, build around weapons and relics, then head back into randomized encounters. The difference is the crowd. A normal four-player roguelike can survive on party chemistry. 33 Immortals needs readable arenas, clear telegraphs and enough shared responsibility that one lost player does not make the whole screen collapse.
That scale could be its hook or its problem. Co-op games live on friction: matchmaking, communication, queue times, party size, disconnects and how much patience players have when strangers make mistakes. Thunder Lotus has been unusually direct about the design answer, pushing instant access and non-verbal coordination as part of the game's identity.
Thunder Lotus is taking a very different swing
The studio history is part of the appeal. Thunder Lotus broke through with Jotun in 2015, followed with Sundered in 2017 and became far better known after Spiritfarer in 2020. In a January press release about the Steam version, the studio said Spiritfarer had reached more than 7 million players worldwide, while 33 Immortals had passed 1 million players since its Early Access launch.
Spiritfarer built its reputation on gentle management, grief and handcrafted animation. 33 Immortals keeps the studio's hand-drawn look, but points it at something much louder: Divine Comedy-inspired fantasy, combat readability and online systems that have to work with dozens of people in the same fight.
That contrast is what gives tomorrow's launch texture. Thunder Lotus is not simply following Spiritfarer with another cozy game or making a safe sequel to its best-known success. It is using the trust earned from emotional, authored indies to chase a multiplayer format most small studios would avoid. If 33 Immortals works, it gives the studio a second identity: not just the Spiritfarer team, but a developer willing to make online co-op feel illustrated, theatrical and strange.
Platforms, saves and the Steam arrival
Tomorrow's release is also a platform reset. 33 Immortals first arrived in Early Access in March 2025 on Epic Games Store, Xbox Series X|S, the Xbox app for Windows PC and cloud, with availability through Xbox Game Pass Ultimate and PC Game Pass. The 1.0 launch adds Steam to that picture while bringing the existing Xbox and Epic versions up to full release.
Thunder Lotus' launch FAQ includes a few save details worth knowing before jumping in. Steam demo progress carries over into the full Steam version. Saves from the experimental Steam playtest branch do not carry over, and Early Access saves from Epic or Xbox cannot be transferred to Steam. Cross-platform play is supported between Steam, Epic and Xbox players.
That keeps the cleanest route simple: play where your progress already lives unless Steam is the version you tested through the demo. Cross-play should make the wider launch less fragmented, especially for a game where healthy matchmaking matters more than usual.
The timing puts 33 Immortals in the middle of a busy co-op week. Our new games worth watching this week preview also flagged SAND: Raiders of Sophie and STARSEEKER: Astroneer Expeditions, both of which are chasing group-play audiences from different directions. 33 Immortals has the sharpest release-day question of the three because its whole design depends on making a giant group feel manageable.
June 10 will show whether that promise holds outside Early Access. The game has the elevator pitch, the platform spread and the studio pedigree. Now it needs enough rebels online at once to make 33 feel like a feature, not a number on the box.
