Slay the Spire 2 public beta: how to join, switch back and keep your saves
Join or leave Slay the Spire 2’s public-beta branch on Steam, back up your saves, and get friends onto the same version for co-op.
Build a deck as you climb the Spire, choose which cards and relics to carry forward, and take on enemies solo or with friends online.

Start on Steam’s default branch for the regular Early Access build. Switch to the public beta if you want to try The Fool, Blitz or Dread. If you already have a run underway or play co-op with friends, check your saves and the group’s Steam branch before switching.
