What "L4D2 + Half-Life 2" means here
Valve campaigns that mashup queries join to other owned shooters or sandboxes. The other half of Portal Life: City 17 content joined to Portal. Together they are the L4D2 + Half-Life 2 mashup slot.
Melty does not need a celebrity mashup name for this query. L4D2 + Half-Life 2 is two owned games and one Play button.
Left 4 Dead 2 is co-op FPS. Half-Life 2 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 / Half-Life 2 files back.
Want a custom L4D2 + Half-Life 2? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

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