How would I create a 4 camera local multiplayer game?

I need to create a 4 player endless runner with 4 cameras rendering out on top of each other in “strips”. I’ve looked into split screen and all I can manage is 2 players by using the Normalize view port option which from what I gather is only suitable for 2 cameras. I was hoping someone could help me out here by either explaining a method i could use or point me in the right direction of one? I’m pretty new to this so any help would be appreciated.

I’m not worried about the different keyboard controlling, I’ve a custom controller set up for that.

create 4 cameras in the scene and change their rects
