Slay the Spire 2 early access broke records on Steam — and broke Steam

Slay the Spire 2 is absolutely slaying. The roguelike deck-builder, released in early access on Windows PC on Thursday, is having one of the biggest launches of 2026. Not only did its launch temporarily crash Steam, but it peaked at more than 400,000 concurrent players — the most for any roguelike on Valve’s PC storefront.
