## How Melty uses Left 4 Dead 2

Valve campaigns that mashup queries join to other owned shooters or sandboxes.

Left 4 Dead 2 is a co-op FPS 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.

You can still pair Left 4 Dead 2 with another owned game and publish the mashup with Claude Code or Codex.

## 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 Left 4 Dead 2?

No. You need your own copy. Melty opens the store if Left 4 Dead 2 is missing.

### Can I mash Left 4 Dead 2 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.
