Screeps: World
“Screeps” is a wordplay for “scripts” and “creeps.” It is an MMO RTS game for programmers in an open persistent shared world. Each player uses JavaScript (or compilers of other languages into JavaScript) to write AI of his or her colony of units (“creeps”) which live and operate in real time even while the player is offline. The game world is generated procedurally and consists of rooms. Players compete for controlling these rooms by mining resources, developing infrastructure, and commanding armies. Screeps can also be called a sandbox game for programmers since it has no definite goals. Ins
Screeps: World is an open source MMO strategy sandbox game for programming enthusiasts. You control your colony by writing JavaScript code that operates 24/7 in the huge persistent online open world.

Official announcements, newest first. Posted on Steam.
- Community Announcements10th Anniversary and Free SeasonFriends, we have something to celebrate! 10 years ago, on June 20, 2016, after a crowdfunding campaign and the development of an early browser prototype, we launched Screeps in Early Access on Steam. A lot has happened since then: we've shipped many different features, expanded the world, launched a new game Screeps: Arena, and our team has weathered quite a few ups and downs. But we're proud t...

- Community AnnouncementsSeason 8 starts on March 1stFrom now on, we will start restarting the Seasonal World every 3 months, as we promised earlier in our roadmap. The Seasonal World is a parallel realm where all players start on equal footing from a clean slate. All players have GCL/GPL equal to 1, and everyone has a fixed 100 CPU from the very beginning of the season, which does not scale based on GCL. Each season will have its own slight diff...

Why Screeps: World mods break
A mod is compiled against one version of a game. When the game updates, anything that reached into the parts that moved stops working, and it usually stops working silently rather than with a message that explains itself.
That is what the table above counts. It is not a guess: each row is a mod the community has reported as broken by that specific release. The number is a fair measure of how disruptive an update was, and it is the reason people delay updating a game they have modded heavily.
Common questions
Does IndexGG host Screeps: World mods?
No, and it never will. Every download link points at the author's own page on Nexus, GitHub, CurseForge or wherever they published it. We index the ecosystem; the files stay with the people who made them.
Where does the compatibility data come from?
From the communities that maintain it in the open, not from guesswork. Each claim carries how it is known, so a reported breakage is never presented as though the author said it.
Why is a mod listed as broken when it works for me?
Compatibility depends on your exact game version and the rest of your load order. A mod marked as broken in one release may work fine on an older one, which is exactly why the version is recorded next to the claim rather than a bare yes or no.
