Hint: Defeating Zombies If a Zombie is unaware of you, a single flashbomb will kill it. If it is aware, two are all that is required.
Hint: Defeating Keeper Guards Use a mine or be extra careful when sniping Keeper Guards. If sniping, you must hit them in the back of the head. If you are stealthy enough, you can try backstabbing them, because the blackjack has no effect on them.
Hint: Getting to the sunken Citadel in the docks When you first arrive at the docks, go towards the store. Stop immediately after you pass the Quarantine gate. There is a box in front of you. Destroy it. Go down the ladder and follow the stairs.
Hint: Surfing Garrett Slightly tilt Left Analog stick to glide across the floor and it will appear that Garrett is surfing.
