About This Game

Welcome to REK 

Climb the leaderboard for a chance to pilot a robot at our next event in August 2026.

Real Robot Fighting, Real Robot Simulator

THIS IS NOT A GAME, IT'S A SIMULATOR. The simulator is driven by the same neural nets that power our real humanoid robots. Get good at the sim, get good at real humanoid fights.No canned animations. Just physics-based humanoid combat: every punch, block, and stumble governed by real physics and self-balancing AI.

Play the sim. REK the competition. Become a real pilot.

Flatscreen or VR, Steam Deck or PC, keyboard or controller, you embody your machine. Everything from the movement to the keybindings is designed to make you a better pilot in real life.Master your robot's weight, momentum, and balance to dominate.

Today, you start with our modded version of a Unitree G1. Sooner than later, that won’t be the only robot you get to pilot. Expect the unexpected.

There’s a live arena with a queue. The scoreboard counts every clean hit, rounds are on the clock, and ties go to sudden death. There’s always a fight waiting for you. Every hit, every win takes you higher in the championship leaderboard. The best pilots won't just win the game, they'll earn the chance to pilot a real humanoid robot at a live REK Event.

So are you up for the challenge? Are you made for the combat sport of the future? Only one way to find out.
