Play a Outer Wilds + Portal mashup
Melty lets you combine games in your library. This page is the search URL for a Outer Wilds + Portal mashup. Time-loop exploration mashed with Portal chambers.
A short exploration loop that mashups can join to other owned puzzle or space games. Portal gun puzzles; featured in Portal Life with Half-Life 2.
Melty does not give you Outer Wilds or Portal. If a copy is missing, the app opens that game's store. There is no charge for Melty or for the mashup itself.
What Play does for this mashup
Press Play. Melty downloads Outer Wilds + Portal, installs the files the mashup needs, and starts the host game. That is the whole setup path — no separate Vortex profile, no hand-copied folder.
When you uninstall the mashup, Melty puts every file back as it was. Report a mashup from its page if an upload looks wrong; every upload is checked for dangerous files.
Friends and publishing
If the mashup is multiplayer, Play also gives you an invite link. Keep it private, send it to friends, or open a public lobby.
To make a variant, copy Melty's instructions into Claude Code or Codex and describe how you want Outer Wilds and Portal to meet. The coding agent builds the mashup and publishes it.
