About Screeps: World

Screeps: World is an open-source MMO strategy sandbox in which you program a colony to operate in a persistent online world. You write JavaScript AI that controls your units continuously, including while you are offline. Your colony can harvest resources, build units, conquer territory and trade with other colonies. Expanding your territory increases your influence and ability to expand further, but other players may compete for the same land.

Program your colony

Your units can react to events without your direct participation if you have programmed them to do so. They can mine, build, defend and conquer while you are away, so you can check on your colony occasionally rather than play constantly. The game’s pace ranges from 2 to 5 seconds per tick, depending on the world shard, giving you time to debug scripts in the live world. On a private server, you can develop and test at up to 10 ticks per second.

You can edit scripts in the in-game editor or in an external IDE. JavaScript is supported, along with other languages through WebAssembly: C/C++, Rust, TypeScript, Go, C#, F#, Kotlin, Swift, D, Pascal and Zig. Basic programming skills are sufficient to get started, while experienced developers can put their skills to the test.

A shared strategy world

Units belonging to all players coexist in the same real-time persistent world and follow the same rules. The game includes unit types, base building, resource mining, territory control, an economy, manufacturing, transport, logistics and trading. The quality of your scripts—not the time you spend playing—determines how well your colony performs.

Servers and access

The starter package includes permanent MMO access with a 20 CPU limit. On the official server, you can unlock full CPU through a Lifetime CPU unlock or an in-game CPU Unlock consumable, which can be bought with in-game credits. A separate CPU-limited world shard lets players who have not bought an unlock compete on equal terms.

You can also host your own server, modify its rules and play with friends over LAN or the internet. The server is open source.
