Witcher 3 + Fallout 4: The Witcher 3: Wild Hunt + Fallout 4

Melty lets you combine games in your library. This page is the search URL for a The Witcher 3: Wild Hunt + Fallout 4 mashup. Monster contracts mashed with the Commonwealth.

Geralt's world as a mashup host or guest next to other RPGs you own. A Bethesda world Melty can combine with other owned RPGs or shooters you already have installed.

Melty does not give you The Witcher 3: Wild Hunt or Fallout 4. If a copy is missing, the app opens that game's store. There is no charge for Melty or for the mashup itself.

Press Play. Melty downloads Witcher 3 + Fallout 4, 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.

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 The Witcher 3: Wild Hunt and Fallout 4 to meet. The coding agent builds the mashup and publishes it.
