Buying Slay the Spire 2 on Steam
Slay the Spire 2 is available on Steam Early Access. You can buy it directly from the Steam store. No physical copies exist. No Epic or GOG release as of June 2026.
Authorized third-party sellers include Humble Bundle, Fanatical, and Green Man Gaming. These sites sell Steam keys at a discount. Prices range from $19.99 to $24.99 depending on sales.
