Tunnel of Love

The Tunnel of Love is the safe room at the end of chapter two and thereafter plays a major role in the third chapter of the Dark Carnival campaign in Left 4 Dead 2.

History
Part of Whispering Oaks Amusement Park, this ride is typically meant for romantic couples. Customers are taken by swan boats through narrow, barely light passages featuring alcoves containing suitably themed dioramas. An age-old fairground attraction, the Tunnel of Love is intended to create a relaxing, socially acceptable and private environment in which couples can cuddle, kiss and make out. Although not featured in the game, such attractions invariably play appropriate music on a loop track.

Current Status
At or just before the time the infection hit and Whispering Oaks Amusement Park was commandeered as a CEDA evacuation center, the ride apparently malfunctioned and had been hurriedly shut down for maintenance and repair that was never completed.

The survivors enter the Tunnel of Love and use the entrance area as a safe room. Thereafter in Chapter Three they fight their way along the tunnel (its lights are still working), enter its maintenance room, drop down into a lower level of the tunnel and finally exit to face the challenges posed by Whispering Oaks Amusement Park's most significant ride, The Screaming Oak.
