About
Welcome to REK

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.
You start with our modded versions of Unitree G1 and Engine AI T800. As soon as real fights use new models, the Sim will also have them.

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.
