Slay the Spire 2 has locked in a March 5 early access launch on Steam after a short delay out of 2025. The new trailer revealed four-player co-op with its own dedicated cards and team synergies. Mega Crit expects a similar timeline to the original, roughly one to two years before a full 1.0 release. Hard to overstate the impact of the original, so this is absolutely a day one situation.
