33 Immortals hits 1.0 on Steam with "Very Positive" reviews and a genuinely strange 33-player co-op hook

Thunder Lotus Games, the Montreal studio best known for the hand-painted afterlife sim Spiritfarer, has pushed its co-op action-RPG 33 Immortals into its full 1.0 release. The launch landed on June 10 across Steam, the Epic Games Store, Xbox Series X/S, and the Microsoft Store, closing out a 15-month early access period and assembling the game's three-world structure as a complete package for the first time.

What's new in the 1.0 build

The premise reads like a fever dream and plays like one too. Up to 33 players simultaneously control damned souls staging a rebellion against God's final judgment, climbing through punishing realms loosely modeled on the structure of Dante's Divine Comedy. The 1.0 version finally ships Paradiso, the third and final world, which Thunder Lotus deliberately held back during early access. There is also a hidden ultimate boss encounter the studio kept sealed for the entire early access run, plus expanded character customization, reworked weapon and enemy balance, and a stack of quality-of-life changes built on more than a year of player feedback.

The session design is what separates this from the usual online grind. Runs last roughly 25 minutes, matchmaking is instant and public, and there is no requirement for pre-formed groups, voice chat, or scheduling. You queue, you drop in with 32 other people, and you fight. It is effectively raid-scale cooperative play compressed into a lunch break, which is a very different proposition from the multi-hour commitment most large-group content demands.

How the lobby funnel actually works

The smartest mechanical decision is the shrinking lobby. All 33 players enter Inferno together. That count drops to 22 surviving souls in Purgatorio, and the newly added Paradiso takes just 11 players into the most concentrated, demanding stretch of the game. Each contraction raises individual accountability without collapsing into the rigid role assignments of a traditional team raid. You are never coordinating with a fixed squad, but your contribution matters more with every realm because the crowd you can hide behind keeps thinning out.

That structure is also why the platform rollout was staggered the way it was. A co-op game that needs 33 concurrent players per session carries an obvious failure mode: too small a player base and lobbies never fill, which has quietly killed plenty of ambitious multiplayer indies. Thunder Lotus avoided that by launching on Game Pass from day one on March 18, 2025, securing a reliable population while the organic base grew on Epic and Xbox. Steam arrived only at 1.0, once a mature player pool already existed. All platforms share a single cross-play matchmaking pool, so Steam newcomers slot directly into the same sessions as Epic and Xbox players rather than fragmenting into separate, sparser queues.

Who it's for

This is aimed at players who want the spectacle and chaos of large-group cooperative play without the logistics tax. If your experience with raid content has been gated behind Discord servers, fixed schedules, and the social overhead of assembling a reliable group, the no-setup matchmaking here removes essentially all of that friction. It also fits players who bounce off lengthy sessions, since a full run resolves in about the time it takes to eat lunch.

It is a harder sell for anyone who prefers tightly authored single-player narrative, which is the lane Spiritfarer occupied. 33 Immortals is the studio's first title built entirely around online multiplayer, and its identity depends on other people showing up. The cross-play pool and Game Pass availability are the load-bearing decisions that keep sessions populated, and so far the launch reviews on Steam sit at "Very Positive," which suggests the structural gamble is holding.
