Dead Center - 3/4: Mall

In "The Mall" the Survivors finally reach Liberty Mall, only to find that the evacuation center there has already been overrun by the Infected. This chapter contains a Crescendo Event in which the Survivors must either open alarmed emergency doors on the first floor or smash the windows of a barricaded store on the second floor, triggering a burglar alarm that attracts Infected hordes until the Survivors get to the security office on the third floor and shut it off.

Trivia

 * The Crescendo Event of this chapter is similar to the one in The Park, which also has the Survivors shutting down an alarm to stop the horde.
