What "Half-Life 2 + MW2" means here
Use Claude Code or Codex with Melty instructions if you want a custom Half-Life 2 / MW2 variant. The agent builds it; Melty scans the upload and lets friends join from a link.
Melty does not need a celebrity mashup name for this query. Half-Life 2 + MW2 is two owned games and one Play button.
Half-Life 2 is FPS. Call of Duty: Modern Warfare 2 is FPS. Melty starts the mashup on Windows. Uninstall restores files. Multiplayer mashups mint an invite link.

FAQ
Can Melty mash Half-Life 2 and MW2?
Yes, if you own Half-Life 2 and Call of Duty: Modern Warfare 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 + MW2 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.
