About

Agree—or build higher.

Play your Slay the Spire 2 co-op run as usual. But the moment you can't agree, the screen transforms into a real Tricky Towers arena. The winner decides.

⚔️ What you're fighting over

| | | |---|---| | 🏺 Relics | Multiple players want the same chest relic? Duel! Everyone else watches live, and consolation rewards are kept. | | 🗺️ Paths | Split votes on the map—the winner's choice goes through. | | 📜 Events | Settle shared decisions on the tower. |

Unanimous and individual decisions work as usual.

🧱 The duel

Race, survival, and puzzle modes – original pieces, spells, and physics

💾 One save for everything

The mashup and the regular game use the same profile: unlocks, stats, history, and started runs count in both. Continue a mashup run in the regular game, and vice versa.
