Screeps: Arena is an online PvP-only game where your script fights other players' scripts autonomously in a 1v1 match-based arena environment.
Mix of strategy and coding
The game features all the strategic depth you expect from a classic RTS, including gathering resources, base building, and creating units. But there's a revolutionary twist: you don't control your units directly. Instead, you play by writing a full-fledged JavaScript that runs on the game servers, autonomously executing your grand strategy.
Easy to learn, hard to master
Only basic programming skills are required to start, but it provides a deep, complex game environment where pro coders can push their skills to the absolute limit. While JavaScript is native, you can use community-supported packages for TypeScript, Python, Rust, C#, Kotlin, the list is growing (see in Steam guides).
A 24/7 competitive arena
Your code will battle other players' scripts in a series of short, fast-paced 1v1 matchups. The system automatically matches you with equal opponents based on your arena rating. Best of all, you can find an evenly matched game instantly, 24/7. Even if no other players are online, the system will use their saved code to provide you with a constant challenge.
Endless challenges
