What "L4D2 + Halo MCC" means here
This is the indexable page for "L4D2 plus Halo MCC mashup" and "L4D2 Halo MCC crossover". The homepage does not add a visual tab for every pair.
Melty does not need a celebrity mashup name for this query. L4D2 + Halo MCC is two owned games and one Play button.
Left 4 Dead 2 is co-op FPS. 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 Left 4 Dead 2 / Halo: The Master Chief Collection files back.
Want a custom L4D2 + Halo MCC? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

FAQ
Can Melty mash L4D2 and Halo MCC?
Yes, if you own Left 4 Dead 2 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 L4D2 + 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.
