Slay the Spire 2 Sold 3 Million Copies in Week One — Roadmap Revealed

One week. Three million copies. Mega Crit's first sales report confirmed Slay the Spire 2 had out-earned every game's opening week in its genre's history — with 25 million runs already started worldwide, and the studio openly admitting it was "beyond thrilled" while noting, in classic Mega Crit fashion, that the journey was just beginning.

The announcement also carried the first post-launch roadmap, and the shape of Early Access's future:

• Continuous balance updates — described as ongoing tuning "based on data and player feedback," a phrase that would soon be tested by the first beta-balance backlash.
• Regular content cadence — new cards, relics, and more, delivered in the game's now-standard update rhythm.
• The Early Access contract — the structure that made the original a decade-long phenomenon, reapplied: visible iteration, community-driven priorities, and no content paywalls (no microtransactions either).

Context for the number: 3 million in a week beat Elden Ring spin-off Nightreign's opening pace and made the spire the fastest-selling roguelike in Steam history — on top of the 570K concurrency record, the global #1 seller slot, and a 9/10 from IGN.

The third-party estimate that followed stretched even further: 5.3 million copies in the first month.
