What "Outer Wilds + Halo MCC" means here
Use Claude Code or Codex with Melty instructions if you want a custom Outer Wilds / Halo MCC variant. The agent builds it; Melty scans the upload and lets friends join from a link.
Melty does not need a celebrity mashup name for this query. Outer Wilds + Halo MCC is two owned games and one Play button.
Outer Wilds is exploration. Halo: The Master Chief Collection 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 Outer Wilds / Halo: The Master Chief Collection files back.

FAQ
Can Melty mash Outer Wilds and Halo MCC?
Yes, if you own Outer Wilds and Halo: The Master Chief Collection. Melty is an AI game masher / one-click launcher, not a store that gives you the games.
Is there an official Outer Wilds + Halo MCC 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.
