Port Finale is the third and last chapter in The Sacrifice campaign. With safety almost within reach, a bridge stands in the Survivors' way. Using the generators will raise the bridge, but the Survivors face their greatest challenge yet. In the end, an ultimate sacrifice must be made.

Campaign
Survivors begin by proceeding down an alley into the garage of a store, where throwables and secondary healing items may be found. When players exit through the front door, they will enter the finale area, which is the same area as the Port with a few changes.

Before starting the finale, it is advised to clear the area of wandering Common Infected. Players begin the finale by starting any of the three generators on the map. This finale is different from all of the others: Every time a generator is started, the Director will spawn a Tank and a horde. Either can arrive first, and sometimes both can even arrive at once. Starting multiple generators will spawn multiple Tanks and hordes at the same time.

It is advised to start from the generator in the middle, since the surrounding area is best suited for fighting the Tank. Players should start the other two generators during a horde, as doing so will delay the Tanks, giving players more time to find a better location to fight them. It is advised not to start up multiple generators at the same time unless the players either want the achievement or are capable of fighting multiple Tanks at once, as multiple Tanks are often difficult to defeat. However, if the players wish to do so, it is advised to regroup at the generator closest to the bridge, as it will take time for the Tanks to arrive at the location. If the Survivors work fast enough, they may be able to kill the Tanks one by one as they arrive, provided they do not all arrive at the same time.

After all three generators are started, the bridge's gate will soon lower, allowing the Survivors to proceed onto the bridge deck. All live Survivors must be either on the bridge deck or above it on the railings before the bridge can be raised. Once all survivors are on the bridge, one of them climbs up the ladder and activates the bridge to raise it.

The bridge will begin to rise, but it will stop, and a survivor will need to jump off the bridge and run to the closest generator to restart it. The players choose a survivor to re-activate the generator whilst the rest of the Survivors provide covering fire from the bridge. The choice must be made quickly, as four Tanks will soon find their way to the Survivors. If the Sacrificer is incapacitated, dragged, charged, or ridden to a location that makes assistance from those on the bridge impossible, the remaining Survivors will need to send yet another Survivor down to restart the generator. After the generator is successfully activated, the closing cut scene will show the Sacrificer surrounded by the Infected and finally being overrun, thus signalling the campaign's end.

When choosing whom to sacrifice, it is advised to choose a player with sufficient health and skill to outrun Tanks and other Infected. If such a volunteer is not available then the Survivor with highest health is the next best option. Throwables are useful at this stage, as Pipe bombs and Bile bombs can lure away the Common Infected allowing a quick sprint to the generator (provided no Special Infected are in the way, or the survivor can dodge them).

This is the only chapter in the game which requires at least two Survivors to be alive at any given time. Moreover, at least one Survivor must be present on the bridge after it has risen. Failure to meet these criteria will result in a loss and the chapter will restart from the beginning.

Versus
Watch out for the Hunter, Jockey, Smoker and Charger. They can incapacitate you and make your sacrifice worthless. Tanks do not have a frustration meter but it may be corrected in a future patch.

The Survivors
Tips A good spot to camp out after activating the generators is at the closed gate of the bridge, and putting the Gas Cans on the road leading to your position. From there, Infected can only attack you by dropping from the rooftop to the side and from the direct front, where you will be able to take them out easily. When the Tank comes, destroy one of the Gas Cans so he catches on fire and keep shooting at him. If he is able to get close enough, jump over the railing to the side and follow the alley back around to the bridge again, shooting the Tank as you go.
 * On this level, you absolutely must stick together. If you don't, you will get mobbed and easily killed by the massive mobs.
 * There are really two tactics to use when going about this level- the first is going about it as if you were doing the Chaos Generator achievement, and splitting up to activate the generators at the same time. This strategy is faster, but, since you will be split up, the Special Infected will only need one opportunity to take down and most likely kill you.
 * The other strategy, which is slower but arguably much safer, is to take the generators one at a time, the whole team activating a generator instead of a single person.

Remember that there will be three hordes and three Tanks before the bridge will lower, then a horde and three Tanks will spawn. As soon as the bridge does lower, have everyone sprint on-board quickly- a good strategy is to have one person move up the ladder and rush to the button while the other three kill off the horde so that they don't get onto the bridge. But be sure no Special Infected snare that one person when he is up on the walkway; that could be disastrous.

The Infected
Tips There is a way of surprising the survivors at the end of the finale when one survivor has to restart the generator. When you become a tank (which everyone on the infected team will), you can jump from the roof of the two-story clubhouse next to the bridge onto the platform where the mounted gun is. Doing so will occupy the survivors with trying to deal with the tank and almost assure the defeat of the survivor attempting to sacrifice himself.
 * As always, be sure to hit the lone wolves. They certainly won't be common on this level, but if the rare chance one Survivor decides to run off, hit him.
 * If the Survivors are trying to get the Chaos Generator achievement, make sure that you attack any of the generators that has ONE person at them.
 * Smokers and Spitters are most effective on the rooftop near the middle generator; also they are good on the open walkway near the generator closest to the safe room.
 * When the moment of Sacrifice comes, send ALL of the Tanks to the generator- if you can incapacitate the one Survivor trying to Sacrifice him/herself, then another Survivor has to come, and so on.

Easter Eggs

 * On the Left 4 Dead version of the Port Finale, when you reach the bar, you will see the same jukebox. The only differences there are is that the buttons on the jukebox have a glow around it, and it can play only 1 song when its started, being a random choice of any of the Left 4 Dead 2 songs from The Passing Jukebox.
 * The generators from The Passing: Port are yellow, unlike on The Sacrifice, they are white.
 * The Angels of Death Graffiti is shown in the beginning saferoom. The Graffiti is also seen in the Crash Course DLC
