Slay the Spire II

Slay the Spire II is the sequel to Mega Crit's genre-defining roguelike deckbuilder, in which you climb an ever-shifting Spire by drafting cards, collecting relics, and battling through procedurally generated encounters where every run is different. Developed and self-published by Mega Crit Games, it was rebuilt from the ground up in the Godot engine (after the studio abandoned two years of Unity work following the Unity runtime-fee controversy). It launched into Steam Early Access on March 5, 2026 at $24.99, featuring five characters (returning Ironclad, Silent and Defect plus the new Necrobinder and Regent) and, for the first time in the series, four-player online co-op. Mega Crit expects the Early Access period to last roughly one to two years while it adds more content, additional game modes and a true ending, and has said the game will never include microtransactions.
