Overview

A major game-changing addition has arrived with Slay the Spire 2, allowing players to team up for the first time as they venture throughout the Spire.

Characters can join forces (up to four players) and combine their strengths to tackle the many fearsome foes and dangers that exist at each floor.

We're still awaiting the full details, so be sure to check back after the game goes live!

How Co-Op Multiplayer Works

While we don't know much yet, here's a quick look at what's been revealed so far.

Looking at the UI from the Early Access trailer, it appears to display your teammates' health bar, (max?) Energy, and hand size in the top left.

slay the spire 2 co-op rest site

Here we can see a co-op Rest Site, and it shows that players will have the ability to choose their own preferred option. Seeing as Regent and Silent have both selected Smith, it seems safe to say that the four choices aren't limited between the party.

slay the spire 2 co-op relic selection

Four different Relics all offered at once? Looks like players will have to choose wisely and potentially negotiate over who gets which one. It's currently unclear if two players can select the same Relic, but based on the teaser, we assume you'll have to share!

No need for mods now, as we'll finally be free to mark and draw on the map to our heart's content.
