1. Quick Answer: Is Slay the Spire 2 Crossplatform?

If you are trying to figure out if you and your friends can buy the game right now and play together, here is the exact breakdown of its multiplayer capabilities during the Early Access phase:

Is Slay the Spire 2 crossplatform?
Console Crossplay	No. During Early Access, Slay the Spire 2 is exclusively available on PC (Steam). Therefore, crossplay with consoles (PlayStation, Xbox, Nintendo Switch) is not currently possible.
PC Crossplay	Yes. Players on Windows, macOS, and Linux (including the Steam Deck) can seamlessly play the 4-player co-op mode together via Steam.
Cross-Progression (Cross-Save)	Yes, within the Steam ecosystem. Your unlocks and run history will sync instantly between your PC, Mac, and Steam Deck using Steam Cloud.

2. Early Access Platform Limitations

Let’s be candid: indie studios almost always launch Early Access titles exclusively on PC, and Mega Crit is following the exact same playbook they used for the original Slay the Spire.

Because the developers will be constantly tweaking card balance, fixing bugs, and updating the Godot engine build based on community feedback, pushing these rapid updates to consoles would be a nightmare. Sony, Microsoft, and Nintendo have strict, time-consuming certification processes. Keeping the game solely on Steam allows Mega Crit to update the game daily if needed.

3. How PC Crossplay Works (Windows, Mac, & Steam Deck)

Just because it isn’t on PS5 yet doesn’t mean there isn’t crossplay. Because Mega Crit built Slay the Spire 2 from the ground up on the open-source Godot engine, the game plays incredibly well across different desktop operating systems.

If you are running a high-end Windows gaming rig, your second friend is playing on an M-series MacBook, and your third friend is sitting on the couch with a Linux-based Steam Deck, you can all join the same co-op lobby effortlessly through your Steam Friends List. The network code handles the different operating systems flawlessly.

4. Cross-Progression & Steam Cloud Saves

For many of us, the ultimate Slay the Spire experience is theory-crafting Ascension decks on a desktop monitor during the day, and doing a quick run on the Steam Deck before bed.

Thankfully, Cross-Progression is fully supported on day one via Steam Cloud Saves. As long as you are connected to the internet, your unlocked cards, Ascensions, and character levels for the Ironclad, Silent, Defect, and the new Necrobinder will sync perfectly across all your logged-in PC devices.

5. Will it Come to Switch, PS5, Xbox, and Mobile?

If your gaming group is strictly on console or mobile, you will have to wait.

Mega Crit has historically ported their games to almost every piece of hardware with a screen (including iOS and Android). Based on their past release cycles, you can expect Slay the Spire 2 to hit the Nintendo Switch, PS5, and Xbox Series X|S when the game officially leaves Early Access and hits Version 1.0 (likely in late 2027). A mobile port for iOS and Android will likely follow 6 to 12 months after the 1.0 console release.

Will the 1.0 release feature full console-to-PC crossplay? Given the industry standard for co-op games today, it is highly probable, though Mega Crit has not officially confirmed it yet.
