The Coaster

The Coaster is the third chapter in the Left 4 Dead 2 campaign, Dark Carnival.

Campaign
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. This area has many smaller rooms and tunnels, and it is easy to get lost. Simply try to follow the path the boats would have taken. 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.

Trivia

 * In the beginning, Rochelle or Nick refers to the Tunnel of Love as "the most relaxing safe room I've ever been in".
 * Occasionally, when a Survivor finds an item or a passage in the Tunnel of Love, he/she will add the term "of Love" to the end of the item. For example: "Frag rounds of Love here."/ "Quickly! Into the Maintenance Tunnel of Love!" is said by Ellis, or, "Airduct of Love," if Rochelle finds an airduct.
 * It is possible to kill the entire team as a Charger in one charge. Simply wait at the top of the coaster, out of the way of the coaster cart itself. After the survivors have activated the coaster and the carts go by, get ready to charge them as soon as they reach the top of the very first incline. If done right you will grab one of them, and send the other flying backwards to be killed or incapacitated.
 * Causing an explosion over the hole that leads from the Maintenence room back down to the Tunnel of Love, I.E. a Grenade Launcher shot, Pipe Bomb, etc. will make the hole larger.
