What is Screeps: World?

An online strategy sandbox set in a persistent world shared with other players. You write JavaScript to control a colony that runs while you are offline, directing units to gather resources, build, trade, defend territory, and expand.

For you if...

+you enjoy coding automated units instead of controlling them directly
+you like open-ended strategy in a persistent multiplayer world
+you prefer improving systems at your own pace

Not for you if...

−you want to play without writing and debugging code
−you prefer fast-paced matches to a slow-moving persistent world
−you want a guided story rather than an open-ended sandbox

Players praise the freedom to program and refine automated colonies in a shared world. Common complaints concern the steep learning curve and weak tutorials. Several players also criticize the developers' response to a reported client security flaw; one reviewer says a fix was later released.
