Jumping Sideways

Hey I'm making an FPS mech game. I have the shooting and most of the AI thanks to Dastardly Banana's weapon scripts package. I just need some help with the dodging.

Did anyone ever play Phantom Crash(X Box) or S.L.A.I.(PS2)? I just want to be able to boost left when I press Q and boost right when I press E.

I can map the buttons to the Unity Input, I just need help with a script, the normal character controller only jumps you along the Y axis in the direction that you're moving. I want it to jump sideways when I'm standing still.
