Slay the Spire 2 Beta Patch With Experimental Modes Planned for Nov. 12
Mega Crit planned to release a major Slay the Spire 2 beta patch on November 12, 2026, adding experimental game modes for single-player and multiplayer. The studio is revealing little, and the main branch gets the older v0.111.0 changes in the same update.
Mega Crit planned to release the next major Slay the Spire 2 update, a beta patch with experimental game modes, on November 12, 2026. It is the first patch to include the modes the studio has kept secret for months.
The developer gave the date in its Neowsletter, calling the release "currently planned" for that day. Mega Crit had not yet posted patch notes on Steam when that newsletter was published.
Details are thin by design. The studio said the new content would have more impact the less it revealed beforehand.
Co-founder Casey Yano confirmed one thing in the newsletter's Q&A: the new game modes will work in both single-player and multiplayer. He would not say how many modes are coming or how they play.
A long gap between patches
Experimental game modes have been on the early access roadmap since launch. In August, Mega Crit listed them as in active development, alongside an alternate Act 2 and a new character. The studio has not said whether either of those arrives in this patch.
The wait has been longer than usual. Mega Crit had been shipping beta patches every two weeks, but the last one, v0.111.0, arrived on August 13.
The team says it has spent the time since then, apart from a one-week studio break, on larger pieces of content. Those could not be built alongside regular balance updates.
Beta branch first
The new content will be exclusive to the beta branch at first while Mega Crit works out the kinks. Players can opt in through Steam by opening the game's Properties menu, selecting Betas, and choosing the public-beta branch.
Players on the default branch also get an update. Mega Crit says the main branch will be brought up to date with everything in v0.111.0.
That includes card reworks, balance changes, performance improvements, Indonesian localization, and low HP idle animations for all playable characters.
Slay the Spire 2 launched in early access on Steam on March 5, 2026. Mega Crit said it sold 3 million copies within its first week.
Co-op has been a large part of that. Yano said many players only play multiplayer and that the studio wants to give the mode more longevity. Additional acts are also in the works.
Mega Crit expects beta players to be sharing balance feedback on the new content by the time its next newsletter arrives.
