- Community Announcements[HOTFIX] Biodome factory heatingThere was an issue with factory heating from biodomes using the non-realistic value on first game-load. This could lead to worlds overheating like crazy. The issue has been resolved. My apologies.
- Community Announcements2026-10-16 Weekly UpdateThis week brings a feature request that had been open for a long time : a proper reward for the first dominion terraform. We now get a one time buff, of varying strength, in addition to the artifacts. I also massively improved equilibration speed. The pop-up is now barely visible in most cases. Equilibration is very fast now. I think everyone will appreciate that. Also a small change to ship au...
- Community Announcements2026-10-09 Weekly UpdateHello! This week I finally release the newest Atlas world. It's a very complex one, so I expect I may need to do some more fine tuning on it in the coming week. Though I do find it very interesting. Credits to Pokey for the original design, which I implemented and modified heavily. We also have a new piece of art! A while ago I promised I wanted to reinvest into more art so I did. I commissione...
- Community Announcements2026-10-02 Weekly UpdateWeekly updates are back! I finally freed myself from what was keeping me busy and have been able to come back to TT. I am working on the next Atlas world which will come out next week. This week we simply have a new advanced research. It's not very powerful and it's very expensive, but it solves something I've been struggling with for a while : what to do with neutron stars. You can't harvest t...

Why Terraforming Titans 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 Terraforming Titans 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.
