The Port

"That...is for Bill!"

- Louis

The Port is the third and last chapter in Left 4 Dead 2 ' s The Passing campaign.

Campaign
When you get out of the safe room, you should encounter the other side of the bridge, with Francis, Louis, and Zoey telling you how to power the generator. This is like the Dead Center campaign, except this time, you have to collect all of the gas cans. Also, every time you have a Tank battle after the first one, they give you one more Tank than the previous Tank fight. Louis, Francis, and Zoey will assist you with gunfire when you are near the generator area when you need help. This is especially useful when the Tank arrives, where you get the opportunity to let them do the task of killing the Tank for you. You still have to get the gas cans yourself, however, because they are on a ledge. Once you receive all the cans, the bridge shall lower like the bridge in The Parish, and then you have to run all the way to the car. If you live, you are rewarded with a scene with the original survivors cheering you on while you get out the city. A strategy you can use at the finale is circling around the map, collecting gas cans as you go. Start from the single gas can inside the building, and work your way around clockwise. This is a great strategy to use with co-op and versus, due to the street in the center being a quick way to fuel the generator, grab ammo, and get extra things from Zoey and Francis.

Survival
Two of the same Special Infected will appear at once sometimes so don't go too far from the original Survivors.

Like Swamp Fever, two Tanks may appear at some points. If this happens ,run to the bridge so Louis can deal with them
