I've been having a lot of fun modding 7 Days to Die (zombie game) using Claude Code. I have a strong development background but I've never worked on games before. Without AI it would be completely inaccessible to me without months of catching up.

7DTD is built on Unity Engine and modding is mostly done with XML/XPath and C#. I have yet to install Unity. I have a CLI setup, including a script to disassemble relevant 7DTD assembly DLLs into C# and copy other info from XML files into a directory in my repo.

This "refs" directory has about 800k lines of C# code and 300k lines of XML. Claude can figure out how to add a feature or fix a bug with a few minutes of searching the refs. At first it took 5-10 attempts to get results that actually worked, but now it's often 1-3.

Here are the mods I've released since early Jan:

- SteelUI: fixes for it to work with the latest game version[1]

- Smarter-Tools: a mod I authored from scratch to add a few tweaks to how tools work[2]

- More-Gore-Continued: has serious performance issues I'm working on - making progress[3] (adult only - requires sign-in)

If there's any interest I'm considering writing up all the details in an article and making the mod repos public.
