Spartan Warfare: Halo: The Master Chief Collection + Call of Duty: Modern Warfare 2

Spartan Warfare is one of the mashups Melty shows on the public landing under Discover. Halo: The Master Chief Collection plus Modern Warfare 2 in one mashup.

Spartans in Spartan Warfare, mashed with Modern Warfare 2. Used in Skate Warfare and Spartan Warfare. Melty starts the game after installing the mashup.

Melty does not give you Halo: The Master Chief Collection or Call of Duty: Modern Warfare 2. 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 Spartan Warfare, 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: Modern Warfare 2 to meet. The coding agent builds the mashup and publishes it.
