Thunder Lotus Games has brought 33 Immortals into full 1.0 release on Steam, and the early response suggests the studio’s unusual gamble is working. The action-RPG has already drawn close to 500 “Very Positive” reviews on Steam, helped by a launch discount of 33% that drops the price to $9.97.
The game stands out not just because of its reception, but because of how aggressively it rethinks co-op scale. 33 Immortals supports up to 33 players at once, casting them as damned souls rebelling against final judgment in a world shaped by Dante’s Divine Comedy.
A raid structure that keeps shrinking
The 1.0 version launched on June 10 across Steam, Epic Games Store, Xbox Series X/S, and Microsoft Store. It marks the end of a 15-month early access period and brings the game’s three-world structure together for the first time.
Those worlds are Inferno, Purgatorio, and Paradiso. Paradiso is the final world that had been held back during early access, and it now arrives as part of the full release.
Big co-op without the usual friction
The structure becomes tighter as progress continues. Inferno starts with 33 players, Purgatorio narrows that number to 22, and the final Paradiso stage is limited to 11 players for a more focused and demanding finish.
Each session lasts around 25 minutes, which keeps the pace brisk and the format easy to fit into short play windows. Thunder Lotus also designed public matchmaking to work instantly, without requiring pre-made groups, voice chat, or scheduled play sessions.
That approach makes the large-scale raid feel more accessible than most multiplayer setups of this size. It is built for quick bursts of co-op rather than only for organized teams that can plan ahead.
What changed in the full release
Version 1.0 also adds a secret final boss fight that Thunder Lotus had kept hidden throughout early access. In addition, the game includes deeper character customization, balance adjustments for weapons and enemies, and quality-of-life improvements shaped by community feedback over more than a year.
Those additions make the full release feel like more than a simple content unlock on Steam. Thunder Lotus used the 1.0 launch to sharpen the core structure and add a new endgame challenge at the same time.
Why the timing mattered
Keeping the game off Steam during early access was not an arbitrary choice. For a title that needs 33 players in a single session, launching too early on Steam could have left matchmaking pools too thin and lobbies too empty.
To reduce that risk, Thunder Lotus added the game to Xbox Game Pass from the start on March 18, 2025, giving the community a steadier player base. At the same time, organic growth continued on Epic and Xbox before Steam finally opened at 1.0.
All platforms now feed into one cross-play matchmaking pool. That means Steam players can join the same sessions as Epic and Xbox users, while Xbox Game Pass provides access without an additional purchase.
A studio best known for something else
Thunder Lotus is a Montreal-based studio previously known for Spiritfarer. The company says it has attracted more than seven million players worldwide, and 33 Immortals is its first project built entirely for online multiplayer.
The combination of an unusual concept, a rare co-op structure, and a careful launch strategy appears to be paying off on Steam. With the 33% discount still in place, 33 Immortals sits at $9.97 and is quickly becoming one of the most distinctive indie multiplayer releases in recent memory.
