A Perfect World/Perk-a-Cola/Double Tap Root Beer

Double Tap Root Beer, abbreviated as Double Tap is a Perk-a-Cola featured in the storyline A Perfect World. It was first introduced in the map Fatherland. It is a significant perk part of the original quartet, alongside Juggernog, Speed Cola and Lifeline Liquor. After consumption, weapons that fire ballistic rounds fire 2 rounds for every round fired, effectively either doubling the damage or the fire rate. If it is fired while hipfiring, both bullets are shot independently, while they will stack on-top of each other while ADS.

The perk significantly increases the damage per second of ballistic weaponry. Combined with the increased damage from Pack-a-Punch make Double Tap an excellent scaling damage perk, dubbing it the "firepower perk". Unlike previous incarnations, it doesn't increase fire rate anymore, making it more generally useful for both low and high fire rate weapons, as well as reducing its crutch-factor.

While it provides important damage that's required for zombies in higher rounds, the perk is essentially a one-trick wonder, as well as useless on non-ballistic weapons such as many wonder weapons and explosives. This causes it to be a perk that synergizes extremely well with specific loadouts, forcing players to take that into account when opting to go for Double Tap.
