Slay the Spire 2 was originally due in Early Access this year, but the developers have announced it's moving into March 2026. Made with Godot and with plans for full Linux support, I'm excited and I do hope the extra time will allow them to make the best of it. The original was simply amazing!
Writing in a Steam announcement post on the original game's store page, they said there's no big dramatic reason as to why. It's down to a mixture of their personal lives (everyone is fine) and they kept saying "wouldn't it be cool if..." too many times so they just need more time to get it ready.
They also put up an official FAQ:
Is the real reason for the delay the timing of the Silksong release?
We got together as a team to determine our new release window before Silksong’s date was announced. The timing just worked out like that, but on the bright side, everyone can keep busy playing Silksong during the wait!
Is the real reason for the delay that you’ve been spending your time on making merch/community events/etc?
Our merch is made by 3rd party partners and our community manager is the primary liaison on our team for collabs like that. No game development was harmed in the making of those plushies! Likewise, anything community-focused that we create, participate in, or promote is generally handled by the CM and doesn’t cut into any game development time.
So is it because you’re adding in a bunch of new features and content?
Yes, in part. Because you know what does cut into game development time? Game development! Compared to Slay the Spire 1's early access launch (and for that matter it's final 2.0 form) this new sequel has a lot more content that we can't wait to share with you. In addition, we want to make sure we're upholding the quality bar that both we and the gaming community have come to expect for Early Access titles.
So what’s so different from StS1?
In case you haven’t been keeping up with our trailers and Neowsletters–quite a lot. There are new characters, more cards/potions/relics/events/etc, more visual polish, more animation and VFX, quality of life changes, entirely new mechanics, and still a whole lot more we can’t tell you about just yet. Although, if you read on to the next section you'll learn about a pretty big one...
When was the game originally planned to launch?
2025! Ok, but in all seriousness, we were initially aiming for a Fall 2025 release window. For now, we’ll just have to savor these moments of anticipation a little longer.
Will this be anything like other games that get repeatedly delayed with no explanation?
No, for one thing, you should never expect radio silence from us. That’s why we’re here talking to you now. And, as opposed to a general release year, we have an actual specific date that we’re aiming for internally and are confident we can hit this time. As you've already heard, it’s releasing on a Thursday, but the exact date will be revealed closer to launch.
So, do you regret the “Still coming in 2025” gag at the end of the TGA trailer?
Demi, the CM, who is writing this, pushed for that one so she can take the fall for it. In her defense, it was pretty funny at the time.
