# How to put one game's content inside another game with universal-modder

Port characters, vehicles or mechanics from one game into a second, like Minecraft mobs in GTA V.

**Who it is for:** Fan with a mashup idea, such as a Warthog from Halo driving around Minecraft

**The problem:** Combining two games means extracting assets from one and wiring them into the other's engine, a project few people finish alone.

**The outcome:** A playable mashup mod where content from game A runs inside game B, with a showcase video.

## Steps

1. Install the plugin and set up your fal key for any new art or audio.
2. Describe the mashup to the agent, naming both games and the one thing to bring over first.
3. Let the mashup-mods skill pick an approach: content port, passthrough mod, or reimplementation.
4. Build and verify one working slice in the running game before adding more.

## Prompt to paste into your agent

```text
Use universal-modder's mashup-mods skill to bring <thing from game A> into <game B> installed at <path>. Start with one working slice and show me a screenshot from the running game as proof.
```

## Caveat

Mashups reuse other studios' assets; the README's contribution rules forbid sharing game files or decompiled dumps, so publish only your own code and generated art.
