## How Melty uses Portal

Portal gun puzzles; featured in Portal Life with Half-Life 2.

Portal is a puzzle 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 Portal include Portal Life, Hollow Knight + Portal, Portal + Minecraft, Outer Wilds + Portal, Mario 64 + Portal.

## 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 Portal?

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

### Can I mash Portal 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.
