I've seen it done in other games through modding (code probably) and I'd like to see done with this game. Looking for either someone to make it or give me insight on how it can be done.
Well, maybe. Not sure exactly what your after. Two players each showing 1/2 a screen on each others screen? Like guppy said, to do it right would be a lot of code. A way that should work is if each player wore a camera, say in a helmet mod like my helmet cam, then it might be possible to project that other players camera as an overlay onto player 1's screen. Never tried it, but in theory it might work.
