The Sequel
What's New in Slay the Spire 2
The sequel adds two new characters, co-op multiplayer, and a wave of new mechanics like Enchantments, Doom, Stars, Forge, and Alternate Acts. Here is where to start.
Five Playable Characters
Ironclad, Silent, and Defect return alongside Necrobinder and Regent — two brand-new classes with unique mechanics like Doom, Souls, Stars, and Forge.
New Mechanics
Enchantments modify cards for an entire run. Quest Cards unlock mid-combat. Afflictions debuff your deck. Alternate Acts split the map in two.
Co-op Multiplayer
Up to four players in online co-op via Steam friends. No matchmaking yet, but multiplayer-specific cards and team synergies add real depth.
