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 rare usable item found only in Left 4 Dead 2. The Survivors agree to obtain a six-pack of cola from nearby convenience store and bring it back to Whitaker, the owner of the gun shop in Dead Center, in return for which he will use a rocket-propelled grenade to destroy a fuel tanker truck that is blocking their way to the Liberty Mall.

When the Survivors open the door of the Save 4 Less store, a burglar alarm sounds which triggers a Crescendo Event. After sprinting into the store to retrieve the six-pack, the player who ends up carrying the Cola cannot use any weapon other then the Cola pack itself in a basic meleeshove attack to bat Infected out of the way during the run back to Whitaker's safe room door. In common with all melee attacks, this action is subject to a fatigue timer whereby melee shove strength is degraded by its frequency of use without rest.

Despite the Cola being contained in glass bottles, the six-pack will crack Infected heads, take gunshots (slivers of glass will fly off) be thrown or dropped with impunity. In a word, the Cola is indestructible.

Like any other holdable item, the Cola six-pack requires four meleeshoves to kill a Common Infected or a single swing to an Infected's spine when the victim is passive and unalerted. Similarly, four melee shoves are required to kill a Jockey, Smoker, Boomer, Hunter, or Spitter.

Meleeshoves with the Cola are ineffective against Boss Infected (Witches & Tanks).
