Within hours of going live, Slay the Spire 2 has reshaped Steam's rankings in a way few indie games manage. The roguelike deckbuilder sequel pulled in 177,000 concurrent players on its early access launch, shattering the previous record for roguelikes by a massive margin. It's also instantly become the platform's top-selling game right now, something all the more impressive given that it had zero pre-order window to build momentum.
For context, Mewgenics held the previous roguelike record at 115,000 concurrent players. Before that, Hades 2 set the bar at 112,000. Slay the Spire 2 didn't just inch past these benchmarks; it nearly doubled them. The original Slay the Spire peaked at around 57,000 concurrent players just months ago. The sequel has already tripled that in its first day.
The player surge was so sudden that Steam's infrastructure took a hit. According to reports, the store experienced a brief outage lasting roughly 30 minutes during launch, with purchase transactions getting stuck in limbo as users rushed to buy the game. The situation resolved relatively quickly, but it's a reminder of just how concentrated demand can get when the gaming community rallies behind a single release.
What makes this performance particularly striking is the sales chart position. Marathon, Bungie's much-hyped multiplayer shooter, had claimed the top spot just hours earlier. But Slay the Spire 2 dethroned it despite an obvious disadvantage: Marathon had been available for pre-order for weeks, accumulating sales before its launch. Slay the Spire 2 became purchasable only at release, yet it still outsold the big-budget FPS in a matter of hours.
It's worth noting that Steam's top sellers ranking measures revenue within a nebulous timeframe of "now," making it somewhat mysterious how exactly the rankings work. What's clear, though, is that player enthusiasm has been overwhelming. As of writing, the game remained the fourth most-played title on Steam overall, behind only Counter-Strike 2, Dota 2, and Arc Raiders, and ahead of Resident Evil Requiem.
What's Coming in Early Access
Mega Crit Games has confirmed that Slay the Spire 2 will remain in early access for one to two years. The roadmap includes expanded content: new cards, events, environments, enemies, and additional game modes. The most significant addition is a new co-op mode that lets up to four players tackle the Spire together, complete with multiplayer-only cards and team synergies.
The developer also notes that the game already contains more content than the original Slay the Spire did in its finished form. The sequel features five playable characters (two brand new), an overhauled card and relic system, and a completely rewritten engine. Mega Crit has invited players to submit feedback and bug reports directly in-game, echoing the community-driven development approach that made the first game such a lasting success.
There's a practical reason to jump in now, too: early access pricing sits at $22.50 for owners of the original game (after a $2.50 discount), but the full version will cost $25 once it exits early access. For players who've already decided they want the game, waiting means paying more.
The Bigger Picture
This launch represents something more than just big numbers. It's evidence that the roguelike deckbuilder genre has genuinely broken into the mainstream. The original Slay the Spire, released in 2017, helped define the genre. Its success inspired countless imitators. But for most of its existence, roguelikes remained a niche category within gaming. Recent releases like Hades 2, Mewgenics, and now Slay the Spire 2 suggest that's changing.
The indie development scene has clearly shifted too. Several other developers deliberately moved their releases earlier or postponed launches to avoid the Slay the Spire 2 launch window. One dev joked that they shifted their game forward so they could actually play Slay the Spire 2 that evening. It's not often that an indie deckbuilder becomes a release event significant enough to alter other studios' plans.
Australian players should note that Slay the Spire 2 is currently PC-only (through Steam) during early access, though console versions are likely once the game reaches full release. Local pricing and availability will likely remain consistent with the international launch.
For now, Steam Deck users on the original game have already gotten a taste, and compatibility reports suggest the sequel should run well. The community's response has been enthusiastically positive, setting the tone for what could be a genuinely significant chapter in the roguelike genre's evolution.
