Paper 2D Local Multiplayer/ Split Screen

I have been looking for videos on this topic but no one seems to know what I am trying to make. I was looking for Paper 2D Local Split Screen. All the tutorials are on 3rd person or first person. If anyone can help please do so…

Usually the tutorials are quite global.

What is the difference between a paper2d game and a 3d one, at the exception that you use a paper 2d character instead of a 3d one ?

None, you use the same tools for both.
