It's not really a question, but a hint the fastest way to beat Red in the train mission is to use the SMG, PP7, or Assault Rifle. Lock on w/ L1, then Bond Focus (square while holding L1), when you hit the circle it moves keep hitting the circle (on Red, not the button) until he falls to the ground then repeat. P.S. Once you hit the circle the first time each cycle he stops shooting @ you.
Good luck! :)
