The Coaster

The Coaster is the third chapter in the Left 4 Dead 2 campaign, Dark Carnival. After leaving the safe room, the Survivors must navigate the shut-down Tunnel of Love. Its dry cement path is littered with stranded swan boats and gangs of the Infected. After exiting the Tunnel through maintenance areas, they emerge into the park proper again. Their path is blocked by the famous 'Screamin' Oak!" roller coaster. To get to the the safe room they must activate the ride and run along the tracks to the other station, which triggers a rolling crescendo. If the Survivors traverse the twisting, climbing, curving, dropping path of the coaster while fighting off the Infected, they can turn the coaster off, ending the event. The safe room is just beyond.
