Sorry guys just tired of getting all the way until the very final boss and dying. I have done this 10 times and think I'm finally rage quitting. I don't know the best way to beat the final boss. Sorry if my language was offensive
I can confirm 100% that this trophy (SharpShooter) is glitched. I completed Chapter 1 and got the same accuracy down to the decimal numbers (an impossibility).
Reinstalled the game and got the trophy first try
