Screeps Arena

Screeps: Arena is an online RTS PvP-only game. Your script fights other players' script autonomously in a match-based arena environment.

All aspects of an RTS game: gathering resources, base building, creating and upgrading units.

You don't control your units directly, you play by writing full-fledged JavaScript that runs on game servers.

Other languages are supported via WebAssembly: C/C++, Rust, TypeScript, Go, C#, F#, Kotlin, Swift, D, Pascal, Zig, the list is growing.

Your code is executed autonomously while fighting other players' code during series of short fast-paced 1x1 matchups.
