## What "Half-Life 2 + Outer Wilds" means here

An AI mashup of Half-Life 2 and Outer Wilds 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. Half-Life 2 + Outer Wilds is two owned games and one Play button.

Half-Life 2 is FPS. Outer Wilds is exploration. 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 Half-Life 2 / Outer Wilds files back.

Want a custom Half-Life 2 + Outer Wilds? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

## FAQ

### Can Melty mash Half-Life 2 and Outer Wilds?

Yes, if you own Half-Life 2 and Outer Wilds. Melty is an AI game masher / one-click launcher, not a store that gives you the games.

### Is there an official Half-Life 2 + Outer Wilds 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.
