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 2nd tier weapon, ammo, 2 meele weapons, and laser sights.

Trivia

 * Save 4 Less is likely a reference to the name of the game.
