Crown Clash

Newest update: Crown Clash is now singleplayer (2026-09-28)

• Crown and Knockout run on your own machine against 3 bots, so fights feel smoother. Multiplayer is off for now while we keep working on it. Also fixed: the blue screen when you entered Sunset Arena, and the missing slash effects there.

Earlier update: Sunset Arena (2026-09-22)

• A new stage rises at dusk — five tiered platforms climb toward a glowing summit where the crown awaits.
• Gentle winds carry distant birds and soft bells across the evening sky, setting a calmer tone for battle.
• The Knockout AI has been refined to make smarter, more aggressive plays on the new arena's geometry.
• Multiplayer matches now run on owned player-controlled fighters, reducing lag and improving responsiveness in real-time fights.

Earlier update: Multiplayer Clash (2026-09-20)

• Fight up to three human opponents online in real-time battles across the sky-island arena
• Create or join public lobbies to queue for matches, or invite friends to private rooms
• Report connectivity issues and lag directly from the pause menu to help improve the beta
• New Knockout mode lets you battle with lives and a countdown timer instead of crown control
• Pause mid-match in multiplayer to catch your breath—the round continues for others

What players say

• @yzykyl · 2026-09-22 · played 29 min · 1 heart: “Played this game with my friend and had so much fun! Timing the heavy attacks definitely felt the most satisfying thing to do especially if I hit multiple opponents. One thing I noticed tho, sometimes when I or the enemy respawns from getting KO'ed, the damage percentage doesn't reset to 0. I don't think that's intentional.”

I also felt like my movement was kinda delayed at times, but Im not sure if it was just me. Still really enjoyed playing it tho!”
