## What "Portal + Terraria" means here

Portal gun puzzles; featured in Portal Life with Half-Life 2. 2D digging and bosses that pair cleanly with other sandbox titles you own. Together they are the Portal + Terraria mashup slot.

Melty does not need a celebrity mashup name for this query. Portal + Terraria is two owned games and one Play button.

Portal is puzzle. Terraria is sandbox action. Melty starts the mashup on Windows. Uninstall restores files. Multiplayer mashups mint an invite link.

## Play, friends, AI

Press Play. Melty downloads the mashup, installs files, and starts the host. Uninstall puts Portal / Terraria files back.

Want a custom Portal + Terraria? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

## FAQ

### Can Melty mash Portal and Terraria?

Yes, if you own Portal and Terraria. Melty is an AI game masher / one-click launcher, not a store that gives you the games.

### Is there an official Portal + Terraria DLC?

No. This is a mashup/mod session. Publish your own variant with Claude Code or Codex.

### What does Play do?

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

### Can I play with friends?

Yes, on multiplayer mashups. Press Play to get an invite link, then keep it private, share it, or go public.

### Is Melty safe?

Every upload is checked for dangerous files. If a mashup looks wrong, report it from its page.
