Rotated by 45° split screen

I want to create rotated splitscreen, how would one go around and create something as shown this image.

It’s not hard to create another camera and move one on top half and one on bottom, but I couldn’t find anything on how to rotate those cameras, some help?

You would have to use Render Textures. So, you would set up two cameras (one for each player) and render them both to texture. Then, programmatically modify one of the textures to “cut” a slice from the texture (in other words, set a bunch of pixels’ alpha to 0). Finally, on your main camera (set it to orthographic) you would render the two generated textures to a quad. Note that Render Textures are a Unity Pro feature, so if you are using indie you are out of luck unfortunately.
