What "Fallout 4 + Outer Wilds" means here
A Bethesda world Melty can combine with other owned RPGs or shooters you already have installed. A short exploration loop that mashups can join to other owned puzzle or space games. Together they are the Fallout 4 + Outer Wilds mashup slot.
Melty does not need a celebrity mashup name for this query. Fallout 4 + Outer Wilds is two owned games and one Play button.
Fallout 4 is RPG shooter. Outer Wilds is exploration. 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 Fallout 4 / Outer Wilds files back.
Want a custom Fallout 4 + Outer Wilds? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

FAQ
Can Melty mash Fallout 4 and Outer Wilds?
Yes, if you own Fallout 4 and Outer Wilds. 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.
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.
