## What "Outer Wilds + Fallout 4" means here

A short exploration loop that mashups can join to other owned puzzle or space games. A Bethesda world Melty can combine with other owned RPGs or shooters you already have installed. Together they are the Outer Wilds + Fallout 4 mashup slot.

Melty does not need a celebrity mashup name for this query. Outer Wilds + Fallout 4 is two owned games and one Play button.

Outer Wilds is exploration. Fallout 4 is RPG shooter. 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 Outer Wilds / Fallout 4 files back.

Want a custom Outer Wilds + Fallout 4? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.
