Useful in both multiplayer battles and campaign mode, crouch jumping should be practiced and mastered.
Crouch Jumping I remember the first time I tried to "crouch jump". I stood in front of a window in Ivory Tower, crouched, and then jumped to see if I went any higher. I tried and tried thinking that the timing must need to be exactly right. In the end I learned that crouch jumping is very simple and easy. Crouch at the highest point of a jump. Remember to continue pushing forward on the left joystick. Pulling your legs in at the top of your leap will allow you to reach places that are normally just out of reach. Make learning the timing of this special jump a priority early on and you'll be rewarded with special sniper spots and stealthy shortcuts in no time.
