About Death Arena
Death Arena is a multiplayer race to 10,000 points, run through a 3D arena full of rival players and three bosses. You fight all of them at the same time, every kill and every boss hit moves you closer, and the first to reach the target wins.
The creator cites the Death Race film, classic arcade combat games and browser multiplayer IO games as inspirations. Claude Code and Cursor were both used to build it on Three.js, and it placed 75th of the 945 entries at Vibe Jam 2026.
The score gives the fighting a direction: you are not only surviving, you are competing for points against everyone else in the arena. With players and bosses in the same space, the action stays crowded and unpredictable.
