Hi, I just got this game engine and i've been playing with it a bit. I do not have any previous experience except using hammer editor a few years back. so I'm learning the ropes and using many of the online tutorials.

 

My question is if it is possible to create a local multiplayer game? like a split screen or even shared screen for 2-4 people. Any help is appreciated! Thank you
