Weapon Ball Fight
The app behind the viral weapon-ball battle clips: build custom fights, let physics run the match, screen-record the chaos.
It's not a game you win — it's a simulator: pick the weapon balls, set the arena, press go and watch them fight with real physics. Screen-record the result and that's the TikTok/Shorts format people keep posting.
How it works
The five-minute tour.
- 1Pick your balls
Each ball has a weapon — sword, dagger, boomerang, unarmed, and more added per update.
- 2Set the arena
Choose maps, behaviors and rules — custom behaviors arrived in the big 11.0 update.
- 3Press play
Balls auto-fight with real physics collisions — hits, combos and knockouts resolve on their own.
- 4Record it
Use your device screen-recorder — the app's whole pitch is shareable fight clips for TikTok, Shorts and Reels.
Modes and toys
What's in the current build.
Free-for-all mode, custom ball behaviors, skins, and an ad-skip ticket option — all in a free app with no in-app purchases. The 11.0 update rebuilt the codebase and reworked how ball types behave, which is why the app is getting a second wave of attention.
Why it's viral
The format that spreads.
Weapon-ball fights are the latest evolution of the 'marble race / ball battle' short-video niche — unpredictable physics outcomes, easy 'who wins?' framing, infinite remix potential. The app is literally built around the record-and-post workflow.
