Halo + Black Ops: Halo: The Master Chief Collection + Call of Duty: Black Ops

Melty lets you combine games in your library. This page is the search URL for a Halo: The Master Chief Collection + Call of Duty: Black Ops mashup. Spartans and Black Ops maps in one multiplayer mashup lobby.

Spartans in Spartan Warfare, mashed with Modern Warfare 2. A COD campaign/multiplayer title Melty can pair with other owned shooters.

Melty does not give you Halo: The Master Chief Collection or Call of Duty: Black Ops. If a copy is missing, the app opens that game's store. There is no charge for Melty or for the mashup itself.

Press Play. Melty downloads Halo + Black Ops, installs the files the mashup needs, and starts the host game. That is the whole setup path — no separate Vortex profile, no hand-copied folder.

When you uninstall the mashup, Melty puts every file back as it was. Report a mashup from its page if an upload looks wrong; every upload is checked for dangerous files.

If the mashup is multiplayer, Play also gives you an invite link. Keep it private, send it to friends, or open a public lobby.

To make a variant, copy Melty's instructions into Claude Code or Codex and describe how you want Halo: The Master Chief Collection and Call of Duty: Black Ops to meet. The coding agent builds the mashup and publishes it.
