Slay the Spire 2 (commonly abbreviated StS2) is the sequel to Mega Crit's iconic roguelike deckbuilder, currently in Steam Early Access. You climb the Spire one combat at a time, building a custom deck of cards, collecting powerful relics, and fighting through randomly generated encounters culminating in act bosses.
