Instructions
Begin a mission on one of the game modes, such as Campaign, Multiplayer, or Zombies. Remember that zombies use their numbers to their advantage and can surround a player who is lying on the ground following the drop shot.
Begin running forward, but don't be afraid to run partially at a diagonal to utilize another dimension against enemies firing upon you. Running around corners is a particularly good time to run at a diagonal and is also one of the best scenarios to perform a drop shot.
Line your aiming reticule up with an enemy or compensate for where the enemy will be when you begin firing, then hold the "dive" button (by default, the circle button). Immediately upon pressing and holding "circle," your aiming will become smaller and therefore more accurate, ensuring that more of your shots hit your enemy.
Pull the trigger, unleashing a spray of bullets that often finishes your opponent off before either player hits the ground.
