Change First Person Controller Controls

Sorry for the dumb question. I’m new at this. I’m trying to make a co-op game. I already know how to do split-screen, but how do you give different controls to different first person controllers?

THANKS - Gallerdude!

If I remember right the first person controller uses two axes, vertical and horizontal, to steer the character. You can make two custom axes, say I-K and J-L and change the code of the another FPS-controller to use them.
