The Necrobinder is the headline new character at launch. This wandering lich utilizes a unique “corpse” resource mechanic where defeating enemies generates corpses that fuel powerful spells . Unlike traditional energy-based classes, the Necrobinder forces players to balance “generator” cards that create corpses with “spender” cards that consume them, creating a completely new strategic layer .
The Defect returns from the first game with upgraded hardware and familiar orb mechanics . Ironclad and Silent round out the launch roster, with The Watcher notably absent but expected later in Early Access . The Regent class has also been teased as another new addition coming soon .
Known Early Access Issues & Hotfix Plans
As with any Early Access launch, Slay the Spire 2 has its share of bugs. The most notorious is the “WWWW” text bug, where all in-game text displays as repeated “W” characters instead of proper words .
The issue affects players using non-English Steam language settings, particularly Swedish, Norwegian, and Czech. The temporary fix is simple: change the in-game language to English in Settings, then restart the game . Mega Crit has acknowledged the bug and plans to release a hotfix soon .
Another reported issue involves Timeline unlocks after certain multiplayer runs, which can softlock progression . This appears to be separate from the localization bug and affects only specific co-op scenarios.
Mega Crit has promised regular updates throughout Early Access, including new cards, events, environments, and balance adjustments based on player feedback . Players can now submit bug reports directly through the game .
What’s Next: Early Access Roadmap
The Early Access period is expected to last approximately one year, with the full 1.0 release planned for 2027 . Console ports for Nintendo Switch, PlayStation, and Xbox will follow after the PC version reaches full release .
