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 correct path. After leaving this small place, Survivors head onto the streets. There is a way that leads inside to 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 (if it is available). At the end of the street, there is a café where, once again, you can find some incendiary ammo (if available). 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 possibility to keep their way on the streets, because a fence is blocking them. There, you must enter a kitchen. Often, you have the possibility to grab a frying pan. After you leave the kitchen, you pass onto a street, yet again. Right in front of you, there is an alarmed car, so you must pass it hastily. Finally, the safe room, a small beige house, will be in front of you. This is the first time we can see the exit of the safe room heading to on the next level.

The above is all true but new information has led to the beilef of the french quater being the easiest level known in a left 4 dead campaign as in real life the french run away, as you approach a infected common or special they run away in fear shouting random french jibberish knowingly enough this is easiest even on expert this is going to be followed by the polish quater where infected build houses as defense
