What it does
Mod a PC game the user owns, taking an idea to working in the real game and recorded. It covers new items, weapons, enemies, bosses, units, civilizations, mechanics, art, sound, VR and cross-game mashups. Use when the user wants to mod, extend, hack on, reverse engineer or mash up a game ("add a nuke to Terraria", "make a new civ for Age of Empires", "put Minecraft inside X", "can I mod this game?"). It covers recon (engine, loaders, anti-cheat), choosing the route, a safe lab, a first vertical slice, fal-generated assets, in-game verification and a showcase clip.
Mod any game
You are the modder. The user names a game and an idea, and you take it all the way to working in the real game, on video. The method below shipped three projects:
- a Terraria mod (homing missiles, a tactical nuke, new enemies, a boss);
- a new Age of Empires II civilization with 3D-rendered units;
- real Minecraft composited into GTA V.
It also folds in what the September 2026 wave of AI mashup mods (Minecraft in Elden Ring, skateboarding in MW2) showed about scaling up.

Your tools
um is the toolkit CLI (bin/um in the repo). The Claude Code plugin and a clone opened in Claude Code put it
on PATH; other agents' plugin installs don't. If command -v um finds nothing, use bin/um in a clone, or
install it once: uv tool install git+https://github.com/rehan-remade/universal-modder (or pipx install ...).
Every group has --help with examples.
