Look up in your preferred web browser undertale multiplayer mod should pop up first ( if not go to mod db undertale together) Download it if it say it may be a virus delete then redownload ( keep repeating if it says that) open the file extract all go to spaghetti installer in the extracted file then it will ask where your undertale is go to that (if its steamowned it should auto appear) install optional files if you want. to add online download crashphalt paste all files into to undertale files delete the crashphalt files after that and go to undertale (heart icon should be at the bottom) and rename crashphalt. It then should be undertale.
