Once you get your weapons up to a level where they really do some damage, it’s time to enhance your abilities in the same way. The Zombies mode in Cold War offers up six different Perks at the start. You can choose from Jugger-Nog, Quick Revive, Speed Cola, Stamin-Up, Deadshot Daiquiri, and Elemental Pop. These Perks can enhance your speed, healing ability, aim, and more. No matter how good you are at taking down Zombies on your own, infusing your character with some Perks will make you that much more lethal.
