The Quarter

The Condos is the fourth chapter of the campaign, The Parish, in Left 4 Dead 2. This chapter has been shown to be home to a crescendo event in which to get across a roof to a balcony that contains a safe room, a parade float needs to be driven to create a bridge between the roof and balcony. The float (when activated) plays a loud, cheery tune that attracts the infected. This tune replaces the usual soundtrack that plays when fighting the horde.

Trivia
The sign "Jules, Fresh Crawfish which can be seen in the picture above, is also present in the Waterfront at the start of the map.
