Slay the Spire 2 launched in Early Access on March 5, 2026, and the numbers are already historic. Developer Mega Crit’s long-awaited sequel to the genre-defining roguelike deckbuilder has taken Steam by storm, peaking at over 180,000 concurrent players on its first day . That’s more than triple the original game’s all-time peak of 57,000 players .
The launch has been nothing short of spectacular. Slay the Spire 2 instantly became the top-selling game on Steam, dethroning Bungie’s highly anticipated shooter Marathon . It’s currently the fourth most-played game on the platform, sitting behind only Counter-Strike 2, Dota 2, and Arc Raiders, and ahead of industry giants like Rust and even Resident Evil: Requiem .
Here’s everything you need to know about the record-breaking launch of Slay the Spire 2.
Record-Breaking Player Count
The player numbers tell an incredible story of pent-up demand. Within hours of release, Slay the Spire 2 peaked at over 180,000 concurrent players, a figure that continues to climb as word spreads . This shatters the previous roguelike record of 115,000 set by Mewgenics just weeks ago .
Slay the Spire 2 Launch Numbers
| Metric | Number |
|---|---|
| Peak Concurrent Players | 180,000+ (and rising) |
| Previous Roguelike Record | 115,000 (Mewgenics) |
| Slay the Spire 1 Peak | 57,025 (during $2.49 sale) |
| Steam Ranking | #1 Top Seller, #4 Most Played |
| Price | $24.99 / 88 RMB |
What makes this achievement even more impressive is that Slay the Spire 2 achieved these numbers at a full $24.99 price point, without any pre-order period or discounts . In comparison, the original game’s peak of 57,000 players came during a massive Steam sale when it dropped to just $2.49 . This demonstrates the incredible brand loyalty Mega Crit has built over the past seven years .
Co-Op Mode & Necrobinder Drive Hype
The launch success can be attributed to two major new features that have captured players’ imagination: 4-player co-op and the new Necrobinder class .
The co-op mode supports up to four players with dedicated multiplayer cards and powerful team synergies that create entirely new deck archetypes . Players can vote together on map paths and event choices, transforming the solitary Spire climb into a shared strategic experience .
The Necrobinder, a sassy lich with a giant reanimated hand companion named Osty, has become an instant fan favorite . Osty acts as a bodyguard, taking damage meant for the player, and can be built up with massive HP or repeatedly sacrificed and resummoned for strategic advantage . The class also introduces Doom mechanics—a stacking debuff that instantly kills enemies when it meets or exceeds their current HP—and Soul cards that provide powerful card draw engines .
The Defect returns with upgraded hardware, joining Ironclad and Silent at launch, with the Watcher expected to arrive later in Early Access . The Regent has also been teased as another new character coming soon .
Steam Dominance & Future Roadmap
Slay the Spire 2’s launch has been so dominant that it briefly knocked Bungie’s highly anticipated Marathon from the top seller spot, despite Marathon having the advantage of a lengthy pre-order period . The game is currently sitting at #4 in Steam’s most-played charts, ahead of Resident Evil: Requiem which peaked at 344,000 but has since settled .
Mega Crit has promised regular updates throughout Early Access, including new cards, events, environments, enemies, and balance adjustments based on player feedback . The Early Access period is expected to last approximately one year, with the full 1.0 release planned for 2027 .
Built on the Godot engine, Slay the Spire 2 offers significantly better modding potential than the original, with official mod support and Steam Workshop integration expected during Early Access . Console ports for Nintendo Switch, PlayStation, and Xbox will follow after the PC version reaches full release .
For players experiencing the “WWWW” text bug affecting some non-English Steam settings, a temporary fix is to change the in-game language to English and restart the game—a permanent hotfix is coming soon .
