HTOTM: FUSION
Firstly, moved to the appropriate board for this. Be wary next time please.

Secondly to answer your question:
I too was hard-stuck on making this work but with the help of a friend I figured it out.
Essentially, you have to use a unique opener during your multiplayer games. It should show up on here: https://forum.toribash.com/tori_opener.php


You're free to update the name of that specific opener you've just "made" and it should show up in-game almost immediately, the next time you use it.

Additionally, I've found an old thread relating to this: https://forum.toribash.com/showthread.php?t=615300

Where this: https://forum.toribash.com/showthread.php?t=613454
and this: https://forum.toribash.com/showthread.php?t=160426


would be of more help.

If anyone would like to post additions to this, please go ahead. As I've only shared my experience.
