## What "Rust + L4D2" means here

Queries like "Rust x L4D2" and "combine Rust and L4D2" map to this URL. Melty is not a pirate copy of either survival or co-op FPS title.

Melty does not need a celebrity mashup name for this query. Rust + L4D2 is two owned games and one Play button.

Rust is survival. 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 Rust / Left 4 Dead 2 files back.

Want a custom Rust + L4D2? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

## FAQ

### Can Melty mash Rust and L4D2?

Yes, if you own Rust and Left 4 Dead 2. Melty is an AI game masher / one-click launcher, not a store that gives you the games.

No. This is a mashup/mod session. Publish your own variant with Claude Code or Codex.

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.
