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

FAQ
Can Melty mash Half-Life 2 and L4D2?
Yes, if you own Half-Life 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 Half-Life 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.
