The Waterfront

The Dock is the first map of the campaign called "The Parish" of Left 4 Dead 2. This is the first named level that is known. A video of this campaign can be seen here. The part 2 is here.

Walkthrough
Apparently, the Survivors start from a dock which leads in front of burning houses. There are two paths - left, which heads to a dead end where incendiary ammo lies, and right, which is the good path. After leaving this small place, Survivors head on to the streets. There is a way that leads inside of one of the town's houses. In a video from E3, one of the survivors found a pistol and some ammo there. Right at the bottom of the window, Survivors can grab an axe. At the end of the street, there is a café, where, once again, you can find some incendiary ammo. After getting inside of the café, there is a small door and a corridor which leads to the backyard. At this place, we can see the first "alternative path" of the new director. In one of the video of E3, the Survivors have no choices to progress on the streets again, but in this video, they are just walking in the backyard, with no possibilty to keep there way on the streets, because a fence is blocking them. There, you must enter in a kitchen. Often, you have the possibility to grab a frying pan. After you leave the kitchen, you pass on to a street, yet again. Right in front of you, there is an alarmed car, so you must right pass it hastily. Finally, the safe room, a small store, will be in front of you. This is the first time we can the exit of the safe room heading on the next level.
