The Coaster

Walkthrough
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.

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.
 * One of the Survivors states in the Tunnels of love: "This the longest tunnel of love i've ever been in
 * Funny part in the safe room is when Coach says "we are in the tunnel of love stay close" and ellis says " Lets define what you mean by close"
 * Occasionally, Nick will say that a sign in front of the Tunnel of Love said "Cousins only day today," likely a reference to a Southern stereotype.

Tactics

 * In the tunnel of love watch out for the holes in the ceiling, where the special infected lurk.
 * When you come to the coaster use melee weapons against the horde:use any sharp weapons.
 * Straying from the tracks can easily mean death for a survivor team.
