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
As the Survivors leave the Saferoom, go down the alley into the garage of the store, here may contain some Throwable items and secondary healing items. Exit through the front door, and you will enter the finale area, the same area during the Port with a few changes.

Before starting the finale, it is advised to clear out the area of wandering Common Infected. After that, starting any of the generators will start the finale. This finale is different from all of the others: Every time you start a generator, the Director will spawn a Tank and a horde, either the horde first, the Tank first, or both arrive at the same time. 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 this surrounding area is best for fighting the Tank. Try to start the other two generator during a horde, this will delay the Tanks and buy you some time to find a better area to fight the Tank. Don't start up multiple generators at the same time unless you want the achievement, or are capable of fighting multiple Tanks at the same time, as multiple Tanks often make a mess. However, starting all the generators at once, and everyone running back to the one closest to the bridge may buy some time as the Tanks still have to make their way over. If the Survivors work fast enough, they may be able to kill the Tanks one by one as they arrive, providing they do not all arrive at the same time.

After all generators are started, the bridge gate will soon lower down, allowing the Survivors to go onto the bridge deck. All alive Survivors must be at least either on the bridge deck or above it on the railings before raising the bridge, otherwise it will not raise. After that, one of the Survivors will have to climb up the ladder and activate the bridge to raise it up.

However the generator in front of the bridge will break down halfway, and it's now time to make the sacrifice. Choose a Survivor to re-activate the generator whilst the rest of the Survivors provide covering fire. The choice must be made quickly, as four Tanks will soon find their way to the Survivors. If the Sacrificer is incapacitated or being dragged/carried/ridden away to somewhere that makes rescue impossible, the remaining Survivors will have to send yet another Survivor out to complete the job. 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 who 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 only other viable option. Throwables are useful at this stage, Pipe bombs and Bile bombs can lure away the Common Infected allowing a quick sprint to the generator (providing no Special Infected are in the way).

This is the only chapter in the game which requires at least two Survivors to be alive at the same time and at least one of them has to be present on the bridge at its conclusion (so that the bridge can be lowered and the generator restarted). If the Survivors fail to do this, it will count as 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
