## What "Portal + Lethal Company" means here

This is the indexable page for "Portal plus Lethal Company mashup" and "Portal Lethal Company crossover". The homepage does not add a visual tab for every pair.

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

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

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

## FAQ

### Can Melty mash Portal and Lethal Company?

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

### Is there an official Portal + Lethal Company 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.
