What "Red Dead 2 + L4D2" means here
Red Dead 2 + L4D2 is the search people type when they want both games in one session. Melty is the AI game masher: you own Red Dead Redemption 2 and Left 4 Dead 2, press Play, and it installs the mashup then starts the host.
Melty does not need a celebrity mashup name for this query. Red Dead 2 + L4D2 is two owned games and one Play button.
Red Dead Redemption 2 is open world. Left 4 Dead 2 is co-op 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 Red Dead Redemption 2 / Left 4 Dead 2 files back.
Want a custom Red Dead 2 + L4D2? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

FAQ
Can Melty mash Red Dead 2 and L4D2?
Yes, if you own Red Dead Redemption 2 and Left 4 Dead 2. Melty is an AI game masher / one-click launcher, not a store that gives you the games.
Is there an official Red Dead 2 + L4D2 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.
