What "Portal + GTA V" means here
An AI mashup of Portal and GTA V still needs legal copies. If either install is missing, Melty opens that store instead of inventing the game.
Melty does not need a celebrity mashup name for this query. Portal + GTA V is two owned games and one Play button.
Portal is puzzle. Grand Theft Auto V is open world. 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 Portal / Grand Theft Auto V files back.
Want a custom Portal + GTA V? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

FAQ
Can Melty mash Portal and GTA V?
Yes, if you own Portal and Grand Theft Auto V. Melty is an AI game masher / one-click launcher, not a store that gives you the games.
Is there an official Portal + GTA V 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.
