- Double Tap Root Beer Jingle

Double Tap Root Beer, increases the rate of fire of all weapons by approximately 30% and is based on the Perk Double Tap. It also removes the firecap on semi auto weapons on the iPhone version of zombies. Being the most risky, as it increases rate of fire and Bouncing Betty speed like Double Tap, however many weapons have high rates of fire anyway. This can cause ammo to be drained at an alarming rate if not used properly. This effect is the most noticeable on weapons like Submachine guns, which often have a high rate of fire. The effect is also amplified by the Pack-a-Punch Machine as many of the upgraded weapons gain an increased rate of fire. But one the other hand you can put more bullets into the enemy(zombies,stinky crawlers,hellhounds) in less time giving you the advantage to shoot and run. This perk costs 2000 points to buy.

It is also very useful to have the Speed Cola Perk, because of the fast depletion of a magazine.

It is important to note that it may be disadvantageous to use this perk depending on the level and guns owned. For example, using it on earlier rounds is not helpful much, as it often wastes ammo. It is more useful on weapons with a lower rate of fire in the earlier rounds.

Double Tap Root Beer is preferably the last perk that should be bought out of all four perks, as Juggernog and Speed Cola (Quick Revive if playing with 2 or more players) can be bigger life savers than Double Tap.

However, Double Tap Root Beer is beneficial for users that are using Pump-action shotguns, whthumb|250px|left|Double Tap Themeich have a low, manual fire rate. This allows the player to spray a volley of buckshot into a crowd of zombies at a fast rate, and when combined with Speed Cola to decrease reload time, benefits campers using the M1897 Trenchgun or the Stakeout.

It is quite odd that Double Tap affects fire rate when you drink it, due to the fact that when you consume one of the Perk drinks, it should somehow affect the player only and in no possible way affect the gun function itself. Although this could be explained as the perk drink might make the characters fingers move faster thereby increasing fire rate. It's main colors are brown and yellow.
