Cola

"But in my haste, I forgot cola!"

- Whitaker "Cola for guns, I think this is like the reverse of what my school did."

- Ellis

The Cola is a usable item in Left 4 Dead 2. It is obtained for Whitaker, the owner of the gun shop in Dead Center, as a proposition he offers the Survivors: get him the Cola, and he'll clear the path to Liberty Mall. Survivors are required to retrieve some from a nearby Save 4 Less store, which triggers a Crescendo Event when you break in. Whilst holding it, you will not be able to use any weapon other then the basic melee shove attack, which, like any other melee shove attack, is affected by the fatigue timer. Despite the bottles being made out of glass, it can be safely thrown or dropped, allowing the survivor to use their guns and pick it up later.

The Cola, like any other holdable item, requires four melee shoves to kill a Common Infected, or a single swing to the back when not alert. Against a Smoker, Boomer, Hunter, or Spitter, it will require four melee shoves to kill them. Against a Charger, Witch, or Tank, melee shoves are incapable of killing them, due to this a primary or secondary weapon should be used instead.
