The 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. This chapter seems to have an increased amount of horde attacks, often running into them non-stop even on Normal difficulty.
