SAVE YOUR NUTS (EP)

I was able to get this (along with Nutworking and Save your Nuts) by doing the following:

Set up a local game of save your nuts on backyard.

Make it 4v4 (despite the description saying alone), with your teammates difficulty set to unfair, and the 4 opposite team members set to hard.

Start the game and first to 5 wins. I camped by the other teams goal and hit them if they were about to score and if I got the nut I threw it across the map with .

I have not tested this thoroughly so I do not know why it unlocked for me even though I had a team, but if this does not work for anyone please let me know so I can update/delete the solution.
