Slay the Spire 2 Drops 15 New Multiplayer Cards and They’re Absolutely Wild

Mega Crit just dropped a massive update for Slay the Spire 2’s co-op mode, and if you’ve been playing with friends, you’re going to want to sit down for this one. We’re talking 15 brand-new cards across every single class, plus a colorless wildcard that might be the most ridiculous thing the studio has ever put into a card game.

The headline grabber here is Midnight for the Ironclad class — a rare attack that smashes enemies for 99 damage straight up. Sounds broken, right? The catch is it costs 12 energy, which is basically your entire turn and then some. But here’s the kicker: every time any player Exhausts a card during the battle, Midnight costs one less energy. Play it right, and you’ve got yourself a nuclear option that actually gets cheaper as the fight drags on.

But the real multiplayer magic is in the support cards. Silent gets Blade Symphony, which hands out free shivs to every teammate. Imagine four players all launching projectiles at once — that’s the kind of chaos this update is cooking up. There’s also Concoct, which lets you slap poison onto another player’s attacks, turning your buddy’s damage dealer into a toxic nightmare.

The Necrobinder class isn’t left out either. Their new card Cacophany deals 66 damage to a random enemy for every 33 cards drawn across all players. In a four-person game where everyone’s cycling through their decks, that number gets out of hand fast. And then there’s Underworld, which applies Doom based on how much damage your allies are dealing — perfect for sitting back and letting your team do the heavy lifting while you reap the rewards.

And we absolutely have to talk about The Ball. This colorless card bounces between players every time it’s played, growing by 15 damage each time it lands. It’s basically a game of hot potato where the potato is a wrecking ball, and whoever ends up holding it gets to unleash increasingly absurd damage. It’s the kind of card that’s going to spawn entire strategies around it.

On top of all the new cards, Mega Crit has also eased up on enemy Block scaling in two-player runs, which should make co-op feel a bit less punishing. The update also streamlines mod support — the first time you install a mod, your unmodded saves get copied over automatically, though they stay in separate folders from that point on.

All of this is live right now on Steam’s beta branch, with a full rollout to the main branch coming soon. If you’ve been on the fence about jumping back into the Spire with a friend, this might be the push you needed.
