## What "Portal + DOOM Eternal" means here

Portal + DOOM Eternal is the search people type when they want both games in one session. Melty is the AI game masher: you own Portal and DOOM Eternal, press Play, and it installs the mashup then starts the host.

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

Portal is puzzle. DOOM Eternal is FPS. 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 / DOOM Eternal files back.

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

## FAQ

### Can Melty mash Portal and DOOM Eternal?

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

### Is there an official Portal + DOOM Eternal 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.
