## What "Fallout 4 + RE4" means here

Queries like "Fallout 4 x RE4" and "combine Fallout 4 and RE4" map to this URL. Melty is not a pirate copy of either RPG shooter or survival horror title.

Melty does not need a celebrity mashup name for this query. Fallout 4 + RE4 is two owned games and one Play button.

Fallout 4 is RPG shooter. Resident Evil 4 is survival horror. 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 / Resident Evil 4 files back.

Want a custom Fallout 4 + RE4? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

## FAQ

### Can Melty mash Fallout 4 and RE4?

Yes, if you own Fallout 4 and Resident Evil 4. 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.
