Any Call of Duty Zombies player with a modicum of experience knows that certain perks are a necessity when grinding the undead-slaying, round-based game mode.

For example, Jugger-Nog is crucial for increasing your health, and Deadshot Daiquiri is crucial for landing quick headshots. Speed Cola is another one of these perks that will help maintain your “gotta go fast” mentality, because as the round number goes up, so does the speed and strength of zombies, so you need to move. And quickly.
