A half-life mod with a very strange idea - an arena where you need your BOTH hands to aim. There are no crosshairs. And unlike COD or other FPS games, when you press the right mouse button, no one will aim for you. You must operate the gun by yourself, or no one can predict where you are aiming at.
It seems I need to lower player's view origin like CS... 64 unit is too high. I want to know how the animation works. And then I meet quaternion, "the easiest hypercomplex number" they said, I thought this thing nealy killed all my brain cells...
