Slay The Spire 2 Beta Patch Adds New Solo And Co-Op Modes

Mega Crit plans to release the next major Slay the Spire 2 beta patch on November 12, 2026. This update will be the first to include experimental game modes that have been kept secret for months.

The developer confirmed via a newsletter that these new features function in both single-player and multiplayer formats. Co-founder Casey Yano declined to specify how many modes are coming or their mechanics, citing a desire to reveal less content beforehand.
