## What "Terraria + Portal" means here

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

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

Terraria is sandbox action. Portal is puzzle. 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 Terraria / Portal files back.

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

## FAQ

### Can Melty mash Terraria and Portal?

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

### Is there an official Terraria + Portal 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.
