Slay the Spire 2 has broken into Steam's all-time Top 20 concurrent player peaks, crossing 574,000 simultaneous users just days after its early access launch on March 5, 2026.
For an indie title from a small team, it is nothing short of remarkable. Mega Crit, the studio behind the game, openly admitted they were not prepared for what happened.
"Our team is TOTALLY blown away by the amount of people who have been playing & sharing their love for the game we've been working on for the past half-decade. We're excited to continue to make StS2 the best that it can be!! Also obligatory joke: we'll getcha one day, Silksong."
Here are the top 20 games on Steam based on peak concurrent users (CCU) (via SteamDB):

Slay the Spire 2 launched alongside Bungie’s highly anticipated extraction shooter, Marathon. On release day, Mega Crit shared a playful congratulations to the Marathon team, joking that they shouldn’t let a “small indie passion project” like Slay the Spire 2 slip by. By the weekend, that joke had taken on a whole new meaning.
SteamDB data showed Slay the Spire 2 hitting a peak of 574,638 concurrent players, while Marathon hovered between 75,000 and 88,000. Co-founder Casey Yano later admitted on his personal account that the post “seems a bit meaner than it was intended,” adding, “To be fair, I didn’t think we’d actually pass Marathon in concurrent users.”
The game even surpassed Resident Evil Requiem's Steam debut weekend peak of 344,214 by over 200,000 players.
Beyond the numbers, the game itself is drawing strong critical praise. It builds confidently on the original while introducing new mechanics, characters, cards, and co-op play. Some balance issues are present, but that is expected at this stage of development.
In a separate interview with Destructoid, Yano was candid about how Mega Crit approaches monetization. The studio is firmly against microtransactions, even with a player base that has made clear they would happily spend money on cosmetics. "We really want players to experience all of the same content as discussion of game content and balance is sort of our lifeblood," he said.
On the modding side, the team is equally supportive, with Yano noting that "reducing friction" for modders is a key priority, "so players have more resources and easier entry points to work with mods."
