## How Melty uses Fallout 4

A Bethesda world Melty can combine with other owned RPGs or shooters you already have installed.

Fallout 4 is a RPG shooter title. Melty is not a storefront for it. The app looks for a copy you already own, then installs mashup files and starts the game when you press Play.

Mashup URLs that mention Fallout 4 include Fallout + Skyrim, Fallout 4 + Cyberpunk, Witcher 3 + Fallout 4, Fallout 4 + GTA V, Fallout 4 + Elden Ring.

## Setup, safety, friends

Play downloads the mashup, installs what it needs, and launches. Uninstall restores the files Melty touched.

Multiplayer mashups mint an invite link. Uploads are checked for dangerous files.

## FAQ

### Does Melty include Fallout 4?

No. You need your own copy. Melty opens the store if Fallout 4 is missing.

### Can I mash Fallout 4 with another game I own?

Yes. Melty's product line is "combine any game in your library and play with your friends."

### What is a mashup?

A mod that joins games into one. In SkyCraft, you play Skyrim as a Minecraft player.

### Do I need the games?

Yes. Mashups run on games you own. If you are missing one, Melty sends you to its store.

### What does Play do?

It downloads the mashup, installs what it needs, and starts the game. Uninstalling puts every file back as it was.
