The Quarter

The Quarter is the fourth chapter of the campaign, The Parish, in Left 4 Dead 2. This chapter has 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 meaning there might be another Resturant chain just like the Burger Tank.
 * As the Survivors progress, the military effort to clean out the Infected by bombing them into submission becomes evident. At various times, the Survivors call out to the military to stop bombing them.
 * The original name for this level was "The Сondos".
 * During a bombing run by the military, a Survivor can take minor damage if they stand under falling debris. An example can actually be seen right inside the saferoom the Survivors start in. If you stand in the corner across from the gun-table, the military will start bombing and debris will fall and damage the Survivor for about 4 damage.
 * In the bar before you get to the Crescendo Event there is a piano in the corner that can be played but it has no effect upon the zombies. This is the same piano that appeared in Left 4 Dead in the Church.
 * The Quarter was going to be a Survival map but was cut for unknown reasons.
