Dark Carnival

"Dark Carnival" is the third campaign in Left 4 Dead 2. It mainly takes place in Whispering Oaks Amusement Park in Griffin County, Georgia.

Description
The campaign starts off after "The Passing", where the Survivors rode on to New Orleans with Jimmy Gibbs Jr's stock car, which they had taken from Liberty Mall. Their luck runs out when they reach a highway filled with "miles" of parked cars that are impossible to drive around, forcing them to proceed on foot. They later notice searchlights coming from Whispering Oaks Amusement Park while heading for the motel. After finding that the evacuation center has been deserted and overrun like in Liberty Mall, they continue to press forward to try to find other Survivors within the park. On the way, they find a helicopter searching for any survivors and manage to get the pilot's attention by setting off the Midnight Riders' concert finale at the Peach Pit stadium.

Behind the Scenes
According to the level-designer from Valve, "Dark Carnival" had different finale, several physical and animated props and also the different area for "The Concert Finale". And for "The Coaster", it was planned as a monorail. The Survivors were to climb to a roof and jump atop the monorail from there. There was also a plan to have a barricade somewhere in the map, but the idea was scrapped.
