- Mega Crit confirmed upcoming features like alternate Acts, Steam Workshop support, and a native Twitch plugin.
- A public beta branch is live right now for testing, alongside a massive wave of new physical merchandise.
A Staggering First Week on Steam
The numbers are officially in, and they are massive. Slay the Spire 2 hit Early Access and immediately took over the PC gaming conversation.
According to the latest developer newsletter, the sequel sold 3,000,000 units in merely seven days. Players have already attempted over 25 million runs—and that is missing early data from launch day.
The team at Mega Crit admitted the response blew past their wildest expectations. Series creator Casey even joked about throwing out his back from overworking during the massive launch rush.

The Road Ahead: No Rush, Just Updates
With five years of development already in the bank, the studio is setting a healthy, sustainable pace. They explicitly stated they refuse to commit to a strict, crunch-heavy schedule.
Instead, new content will hit the main branch only when it is genuinely ready. Players who want an early look at balance tweaks can opt into the new public-beta branch on Steam right now.
Mega Crit has confirmed several major additions coming down the pipeline. We are getting alternate paths for Acts 2 and 3, fresh cards, and entirely new narrative events.
Behind the scenes, the developers are analyzing mountains of data to perfect the game’s balance. They are also building out official Steam Workshop support, multiplayer quality-of-life features, and native Twitch plugin integration.
