Port Finale is the third and last chapter in both The Sacrifice campaign and the Left 4 Dead game. With safety almost within reach, a lowered road bridge near Rayford Port prevents the Survivors taking their chosen sailboat (refer to The Sacrifice comic) out to sea.

The only way to raise the bridge is to switch on a series of portable electric generators, but the noise this creates drives all the Infected in the area into a frenzy and the Survivors face their greatest challenge yet.

The Survivors
At the beginning of the map:


 * Bill will grab an Assault Rifle (Left 4 Dead) or a variant of the same type (Left 4 Dead 2).
 * Francis will grab an Auto Shotgun (Left 4 Dead) or a Hunting Rifle variant (Left 4 Dead 2).
 * Louis will grab an Assault Rifle (Left 4 Dead) or an Auto Shotgun variant (Left 4 Dead 2).
 * Zoey will grab a Hunting Rifle (Left 4 Dead) or an Assault Rifle variant (Left 4 Dead 2).

Method 1
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 one can arrive first, and sometimes both can arrive simultaneously. Starting multiple generators will spawn multiple Tanks and hordes at the same time.

It is advised to start from the generator in the middle of the map since the surrounding area is best suited for fighting the Tank; thereafter, players should start the other two generators during a horde, as doing so will delay the Tanks and give 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 players either want the achievement or are capable of fighting multiple Tanks at once; however, if the players wish take this option, it is advisable to regroup at the generator closest to the bridge as it will take time for the Tanks to arrive at the location. The area also gives good fields of fire and supplies are close at hand. A first-rate team of Survivors working fast may be able to kill the Tanks one by one as they arrive; however, caution is advised, as on rare occasions a Tank might spawn in the building near the bridge where the Survivors are holding out.

After all three generators are started, the bridge's gate will lower and allow the Survivors to proceed onto the bridge deck. The bridge will only rise when all live Survivors are on the bridge and the Tanks spawned by the last generator have been killed. One survivor must follow the on-screen prompt and climb up a ladder from the bridge deck to a panel switch to activate the bridge, the others must stay on the deck whilst this is being done.

The bridge deck will begin to rise, but it will soon stop and instruction will appear to "restart the generator". This is the moment of crisis. Zoey must jump off the bridge deck and run to the closest generator to restart it while Bill, Francis, and Louis provide covering fire. The choice and follow-through must be made quickly as three Tanks will rapidly appear on the scene.

A closing cut scene will show Zoey being killed after she restarts the generator, thus signalling the campaign's end.

Tips

 * On this level, it is generally advisable for teams to stick together. If they do not, isolated individuals are likely to get mobbed and killed by the hordes that spawn after each generator is started.
 * There are really two tactics to use when going about this level. Firstly, there is the highly daring method which involves the team splitting up to start the three generators simultaneously. This strategy is fast but since the team is split up, Special Infected are given an open opportunity to take down isolated individuals who then have little hope of being rescued. Secondly, the team can opt for the safer approach of activating each generator in turn, sticking together for mutual support and facing down the Tank and horde attacks in detail.
 * A good spot to camp out after activating the generators is at bridge's closed gate with gas cans pre-positioned on the road in front. From there, Infected can only attack from two directions: from the riverside tavern on the right and from the direct front―an ideal killing zone. When the Tank arrives, ignite one of the gas cans and whittle down his health with concentrated gunfire. If he gets too close, evasion involves jumping over the railing next to the tavern, running and gunning down the alley and back around to the bridge―as appropriate.
 * It is essential to remember that a horde and Tank will spawn when each of the three generators is started before the bridge is lowered, followed by a grand finale involving a massive horde and three Tanks. As soon as the bridge gate opens, every team member must sprint onto it quickly. At this point, 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 do not swarm onto the bridge. Keep a sharp eye out for Special Infected and gun them down instantly as if any player is snared or incapacitated at this point, the entire plan will be thrown into disarray.

Left 4 Dead 2 Version
The map is unchanged apart from weapon and enemy profiles. Unlike the other Left 4 Dead maps, The Sacrifice was released for Left 4 Dead and Left 4 Dead 2 simultaneously, so there was no time gap between releases for Valve to respond to feedback with map changes.

Survival
Left 4 Dead

The survivors started the generator, yet only to find that the bridge was not coming down, and never would. As the infected swarmed in, the survivors had to realize the message: "No one lives long."

A good spot for obtaining a gold medal would be to have your team hold off by the starting spawn point. Your team can take three Auto-shotguns (mainly for the tanks and the infected that spawn close by) and someone with an Assault Rifle (for infected further away and smokers). Have Gas Cans stored in the generator room behind you and throw one out for every horde that comes.

Left 4 Dead 2 

Your team should take Ak-47s and hold up in the bar. Make sure it is a round that spawns ammo in the bar otherwise restart the round(s) until ammo is in there. You can have gas cans stored behind the counter (to prevent them from getting shot). Have your team conserve healing items because there are no additional health packs that spawn in the Left 4 Dead 2 version of The Sacrifice's Port survival map. Also have one person on your team sit on the jukebox to provide cover for everyone on the counters or the tables and chairs.

It is also possible to camp on the catwalk in the warehouse. Grab ammo from the ammo pile by the warehouse's generator when the area is relatively clear, stand on the railing to avoid Spitter acid, and jump off of the catwalk if you need to run. The Survivors will have a wide enough field of fire that single Tanks can be taken down easily before they reach the players, and twin Tanks can often be defeated with little or no difficulty (Remember, it only takes about half of a clip per Survivor to kill a Tank in Survival mode with an AK-47, and with a fire rate of 461.5 bullets / minute, those twenty shots will be unloaded in a little more than 2.5 seconds)
