What "Outer Wilds + L4D2" means here
Queries like "Outer Wilds x L4D2" and "combine Outer Wilds and L4D2" map to this URL. Melty is not a pirate copy of either exploration or co-op FPS title.
Melty does not need a celebrity mashup name for this query. Outer Wilds + L4D2 is two owned games and one Play button.
Outer Wilds is exploration. 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 Outer Wilds / Left 4 Dead 2 files back.

FAQ
Can Melty mash Outer Wilds and L4D2?
Yes, if you own Outer Wilds 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 Outer Wilds + 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.
