About Robot Royale

You start Robot Royale with bare fists and finish with explosive RPGs, if you survive long enough to reach them. The setting is a dying cyber-city, and the format is a single-player arena shooter. You fight your way up through a series of stronger weapons, and a run is a push to stay alive in the arena while your firepower escalates.

The premise plays on how powerful robots could become in the future once they are combined with AI. According to the creator, it was built with Claude Code, and it ranked 357th of 945 in the final Vibe Jam 2026 standings.

There is no waiting around. A run starts the moment the page opens, and the whole game is contained in a single file built on Three.js.
