The Streets

In "The Streets" the Survivors follow the helicopters from the hotel as they head towards the evacuation center at the mall. This chapter contains a Crescendo Event in which the Survivors must obtain a pack of cola from a Save 4 Less convenience store with an alarmed door for the owner of a nearby gun store, who returns the favor by clearing the roadblock that prevents the Survivors from reaching the mall with a grenade launcher.

Whitaker's Gun Shop
Half way through the chapter, you'll come across a gun store under the ownership of Whitaker that contains 3 or more of every gun in the game(except for the grenade launcher), an ammunition pile, 2 melee weapons, 2 first aid kits, and laser sights.

Trivia

 * Save 4 Less is likely a reference to the name of the game.
 * Save 4 Less may also be a reference to a chain of super markets known as Food 4 Less
 * In Whitaker's store, the Tactical Auto Shotgun is labeled as "fully automatic", when it is only semi-automatic.
 * The gun store might be inspired by Dawn of The Dead (2004), since it also contains a gun shop nearby with a Survivor in it and it is close to the Mall.
 * When you melee several times with the cola, then deliver it to the gun shop owner and let him shoot the barrier and wait a few more seconds, you can hear him open the cola. If done right, you can also hear the cola spewing from the bottle and over him.
