The launch checklist should feel anchored to the Early Access release itself, so it uses the launch art directly.
Slay the Spire 2 entered Steam Early Access on March 5, 2026. This is the baseline page for the current launch state because it separates official launch facts from details that still need live verification.
As of March 7, 2026, the official position is still clear: the game is on PC, macOS, and Linux through Steam, supports up to four players in online co-op, and is expected to remain in early access for roughly one to two years.
Verification note
Verified against Mega Crit's launch post, the Steam store page, the official Steam FAQ, Steam announcements, and SteamDB on March 7, 2026.
Why this update matters

Expect this section to matter more as early access starts shipping regular patches.
What is officially live
Mega Crit's release-date post and Steam store page agree on the headline facts: five playable characters are part of the current early-access version, the game supports online co-op for up to four players, and Steam Deck is already verified.
The official FAQ also confirms fourteen supported languages at launch and says the current build already contains more content than the original Slay the Spire released with.
Five-character roster at the start of early access.
Online co-op for up to four players.
PC, macOS, and Linux support on Steam.
Steam Deck verified from day one.
Two official launch-week hotfix posts already published.
What still looks likely to move
Mega Crit spent much of 2025 showing systems that were still changing, and the January 2026 Neowsletter repeats that message. That means public mechanic pages should include verification dates and update notes instead of pretending the launch build is already final.
This is especially true for card evaluation, unlock specifics, and route-level recommendations. The safest approach is to keep the facts stable and the rankings modest.
Why this page matters
This page helps readers tell the difference between what is official, what is inferred, and what still needs another day or two of early-access evidence.
