Fight Bros

Fight Bros is a free martial arts fighting game from Blue Wizard Digital, the studio behind Shell Shockers and Football Bros. It used to be called Karate Bros, and the old karatebros.io address now leads here. Kick, chop and throw down with your dojo, and send your rivals flying with high kicks and leg sweeps.

From Karate Bros to Fight Bros

A big update in October 2026 brought all new 3D fighters, each with their own stance, punches and kicks. The dojo is back as a stage, the arenas are wider, and every match is now a best of five rounds. Hits also do more damage, so rounds end quickly when someone lands a clean combo.

Simple Controls With Move Hints

Move your bro with the arrow keys or WASD and press the up arrow to jump. You do not need to memorize a move list, because the game shows hints during play for each attack. That makes it easy for new players to start landing kicks right away.

Unlock Fighters and Gear

Challenge the CPU to unlock new fighters and gear, or spar against your friends online. Each unlock gives your bro a new look for the next round. Since every fighter now has a different stance and set of attacks, it is worth trying a few before you pick a favorite.

The developer recommends Chrome, and Fight Bros has also been tested in Firefox and Safari. You can play Fight Bros online for free on Yup7 in your browser with nothing to download, on computers and Chromebooks. Find more free fighting and action games on our Action Games page.
