Released
Screeps: World
An MMO strategy sandbox where players program colonies with real JavaScript. Scripts run continuously in a huge persistent online world, automating harvesting, construction, logistics, trading, expansion and warfare even while the player is offline.
Why it’s a sandbox MMO
Screeps is built around player-authored automation rather than a conventional class or quest path. Colonies gather resources, build infrastructure, manufacture units, trade and compete for territory in a persistent shared world.
What makes it different
You do not directly control units moment to moment: you write the JavaScript AI that controls them. Your code keeps operating while you are offline, making programming skill itself the core progression system.
