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 remote-detonated explosives.

Gun store
Somewhere down the line there is a gun store 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.
 * In Whittaker's store, the Tactical Autoshotgun is labeled as "fully automatic", when it is only semi-automatic.
