## What "Lethal Company + Portal" means here

An AI mashup of Lethal Company and Portal still needs legal copies. If either install is missing, Melty opens that store instead of inventing the game.

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

Lethal Company is co-op horror. 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 Lethal Company / Portal files back.

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

## FAQ

### Can Melty mash Lethal Company and Portal?

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

### Is there an official Lethal Company + 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.
