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.

All campaign walkthroughs are done on Normal difficulty in single player, and are meant to give tips on what to do and generally point out things that might otherwise be missed.

There are, of course, a few key things to always remember:

  • Stop, look, and listen.
    • Being observant might alert you to something nasty ahead of time, like a Witch, Special Infected or Tank, and allow you to prepare yourself.
  • Teamwork.
    • This cannot be stressed enough. Left 4 Dead is supposed to be a cooperative game. Communicate with your teammates, if you're playing with others, or if you're by yourself with the AI, point out things they might otherwise miss. In all cases, watch out for each other and take care of each other. You are not going to survive the zombie apocalypse by yourself.
  • Be ready for anything.
  • Don't panic.

The bridge is in sight, and it's in the way. Three generators to activate, with three times the danger! Can everyone make it?

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), a variant of the same type (Left 4 Dead 2 on PC) or a Hunting Rifle variant (Left 4 Dead 2 on Xbox 360).
  • Louis will grab an Assault Rifle (Left 4 Dead), a variant of the same type (Left 4 Dead 2 on PC) or an Auto Shotgun variant (Left 4 Dead 2 on Xbox 360).
  • Zoey will grab a Hunting Rifle (Left 4 Dead) , a variant of the same type (Left 4 Dead 2 on PC) or an Assault Rifle variant (Left 4 Dead 2 on Xbox 360).

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. A player (the doomed Sacrificer) must jump off the bridge deck and run to the closest generator to restart it whilst the rest of the Survivors provide covering fire. The choice and follow-through must be made quickly as four Tanks will rapidly appear on the scene.

If the Sacrificer is incapacitated or pinned by a Special Infected in a location that makes assistance from those on the bridge impossible, one of the remaining Survivors will need to leave the bridge to restart the generator. After the generator is reactivated, a closing cut scene will show the Sacrificer surrounded by the Infected and finally being overrun, thus signalling the campaign's end.

When choosing the person to sacrifice, it is advised to choose a someone 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 intervene. A litter of gas cans and propane tanks laid across the road intersection just beyond the tavern door can also help create a protective barrier against weaker enemies and buy the sacrificed player valuable time.

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 (or the game will progress if playing Versus).


  • 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 an endless horde and four respawning 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.
  • Watch out for pinning infected. Their ability to render survivors helpless and disrupt the team can ultimately nullify a sacrifice.
  • Unlike in The Passing, The Sacrifice's version of the Port has no defibrillator to revive dead players, so if a teammate is gone, he/she is gone. Defend yourself with caution and stay close to other Survivors. If you are too far away, your teammates may not be able to save you in time, especially on higher difficulties.
  • Tanks do not have a frustration meter, but this may be corrected in a future patch.
  • When playing in co-op mode, one human player can use the Heavy Machine Gun to distract all bot-controlled Tanks that normally would attack the sacrificing Survivor, thus allowing the sacrificer to bypass the Tanks with little difficulty.

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.

The Infected[]

See also: The Boomer, The Hunter, The Smoker, The Tank

Though they might be immune to the Infection, they aren't immune to death; no one is. Work together to make sure they're victims of this rampant virus, one way or another.

Overall Tips

  • Any survivors that choose to run ahead of or fall behind their teammates will be much easier to seriously damage and kill. The farther away they are from their teammates, the more likely they are to be incapacitated or die before their teammates can reach them.
  • The Survivors all have outlines around them, showing their status and location. Green means they're healthy. Yellow means they're hurt. Red means they're low on health. Purple means they've been covered in Boomer bile. You can probably discern which to seek out first if possible.
  • Think like a Survivor. When you play as one, when are the worst times that something could come at you? Exploit that knowledge.
  • Teamwork, as aforementioned. Has a Boomer gotten their bile all over the Survivors? Jump one of them or a clean one. They can't see their teammates' aura until they're clean...and by then, it might be too late.
  • As much as teamwork is a strength for you and your enemies, a lack of it will be their downfall. If you can focus all of your energy on killing one of the Survivors, the rest will be that much easier to take down. Not only will they have one less gun, but they will have three Survivors to your three incapacitating Infected.


  • 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 (there will be at least two such generators).
  • 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 themselves, then another Survivor has to come, and so on.

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 themselves.


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 forever."

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 and everyone else 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)

Easter Eggs[]

  • In 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 that the buttons on the jukebox have a glow around it, and it can play only one song when it's started, being a random choice of any of the Left 4 Dead 2 songs from The Passing's jukebox.
  • The generators from The Sacrifice's Port are white, unlike in The Passing, where they are yellow.
  • There is an Angels of Death graffiti near the door out of the safe room. This graffiti is also seen in the Crash Course DLC.



  • The map is the same map for the finale of The Passing with a few minor differences.
    • The map is almost the same layout as the Survival version since the back streets are sealed off by plywood, a fence, and a concrete barrier. These things are removed by the time of The Passing in campaign mode. The skybox used in The Sacrifice shows the time it takes place could be mid-afternoon while The Passing takes place late at night.
    • Another difference is on the bridge itself. There are a couple of vehicles keeping players from going across the bridge and there is a ladder that leads up to the upper half of the bridge in The Sacrifice. The ladder and vehicles are not present in The Passing. It is unknown how did the vehicles got removed since Zoey, Francis, and Louis didn't expect Coach, Nick, Rochelle and Ellis arriving shortly after. However, it's possible that they fell into the water and drowned when the bridge is being raised, thus explaining why when the L4D2 survivors lower the bridge, the cars are gone already.
    • Some props found in the map, while having the same placement between both maps, feature different models from the ones used in The Passing.
      • The pickup truck parked outside the store at the start of the level features a different model which is drastically different from the one feature in The Passing.
      • The corpses found around the map features based off the Common Infected of the original Left 4 Dead instead of their counterparts from the sequel.
      • The concrete barriers found in both versions of the map features a different (and shorter in height) model.
  • The jukebox from Left 4 Dead 2 appears in the bar, even in the original Left 4 Dead.
  • It is possible to get the MAN VS TANK achievement in the Left 4 Dead version of The Sacrifice, after a player sacrifices themselves due to the presence of multiple Tanks - They will have to damage the tank first, then activate the generator before the tank reaches that survivor, and after activation the tanks will swarm him, but after the campaign ends the game will cause the tanks to die without any reason and therefore attaining the achievement.
  • In the Left 4 Dead 2 version of this map, operating the generators will shift a player's view to third-person and prevent them from walking around, while in Left 4 Dead, they will still be in first-person, able to move and look around freely although the action will be canceled upon not focusing on the buttons anymore.
  • The finale is unlike other finales in both Left 4 Dead games. While every finale would finish once all Survivors have gotten away (or those who were left alive or not incapacitated were able to escape), the finale in The Sacrifice requires at least one person on the bridge and one person to pull off a successful sacrificing. If everyone gets dragged or knocked off the bridge or three Survivors are killed (or kicked, if you use the console command [kick (Playername)]), a message will pop up telling players that they need at least one Survivor on the bridge and one by the generator to finish the finale. This is considered a failure (since the death music plays) and the players restart back in the safe room.
    • When a generator is activated, an in game message will pop up, saying "Generator started. Defend yourselves!" This is slightly different from most other finale which usually says "Rescue is coming. Defend yourselves!" and it also acknowledges that the Survivors are creating their own rescue rather than waiting to be saved (although in The Truck Depot Finale, The Atrium, and The Port, Survivors are also creating their own rescue). Another finale of this kind is The Bridge of The Parish, the message shows "Make your way to the helicopter on the other side."
    • Due to a rare bug, even after restarting the generator, the game will still say "Survivors failed" with the mentioned message despite everyone else on the bridge are alive.
    • Another bug may cause the game to say "Survivors2 failed", instead of "Survivors failed."
  • Survivor bots will never perform the sacrifice. Successfully completing this finale can be very difficult in Single Player since the human player is always forced to perform the sacrifice whilst Survivor Bot gunfire is generally ineffective at dealing with the massive horde plus three Tanks, nor can they use grenades (pipe bombs, molotovs, and bile bombs) and the Heavy Machine Gun on the bridge (this is in contrast to their excellent abilities when providing covering fire in The Passing's finale in Left 4 Dead 2). The trick when playing as a Single Player on Normal is to activate the bridge switch and then to run immediately towards the generator without waiting for any visual or verbal prompts. In this (somewhat counter-intuitive) way, the player ends up close to the generator and in full sprint by the time its engine stalls, thus gaining the necessary extra few seconds needed to restart it before being killed.
    • In other modes with multiple human players with at least one Survivor Bots in the team, the AI component will not leave the bridge once it is raised, and the human players will fail if they are all incapacitated (and not on the bridge) or killed.
    • If a survivor is knocked off the bridge the game will assume they're the ones sacrificing themselves, even if they're a bot, dialogue acknowledging the survivor sacrificing themselves (Such as one telling the other(s) to stay on the bridge) proves this.
  • Some may consider the sacrifice portion of the finale in Left 4 Dead to be more difficult to complete than in Left 4 Dead 2, due to the game lacking Left 4 Dead 2 items like bile bombs and melee weapons.
  • A Heavy Machine Gun is on the bridge for players to use to give the person restarting the generator covering fire. This weapon appears for the first and only time in the Left 4 Dead but reappears in the same role and location in The Passing campaign in Left 4 Dead 2, except in the latter instance is now very effectively crewed by Survivor bot Louis. Said gun emplacement is only effective if at least two players are present.
  • It is possible to wait until the Infected and Tanks are already on the bridge before a Survivor sacrifices themselves. Even though this defeats the initial purpose of the sacrifice, it still counts as a success due to the other Survivors being alive at the end and on the bridge (providing they were not incapacitated on the bridge due to the invading Infected at the time the generator is restarted).
  • When the person sacrificed goes down, the screen showing the survivor takes on a sepia-like tone, similar to the dark orange vision of the Special Infected in Versus mode. The Survivor may automatically get incapacitated before the rocks hit if they were on low enough health.
  • This is the only finale with no rescue vehicle and a guarantee that one Survivor will die.
    • Also, in Left 4 Dead and the Xbox 360 version of Left 4 Dead 2, this is the only finale that checks for Survivor's current location which determines whether the Survivors are alive or dead at the end rather than the Survivor's current status (in this case, any Survivors who are not on a bridge are considered dead, whereas the Survivors who are on the bridge, including the incapacitated ones, are considered 'rescued'); other finales check for every Survivor's status instead of their location (i.e. incapacitated Survivors are deemed dead, even when inside of a rescue vehicle).
  • Through the use of the developer console, noclipping and exploring the outside boundaries of the map shows some differences compared to the same map used in The Passing. The backstreet area that is blocked by a concrete barrier and a fence lacks details and other props. The stairwell by the bridge (the ones used by the new Survivors) lacks a safe room door rendered where it would usually be in The Passing. Going beyond the bridge to where The Passing would normally begin, the buildings are more simple in detail and the park area lacks props. The elevator by the bridge does not have its button rendered either.
    • There are also many notable differences in-map. A few examples being: The concrete blockades are different, the truck outside the shop is different, the generator is white (as opposed to yellow) and facing the opposite direction, the rear door of the boxtruck is closed (not open), and the M2 machine gun is on the bottom platform (rather than the top).
    • Another difference that can be noticed when noclipping is that the beginning of the map is very different from the ending of The Barge. For example, the street is gone and is replaced with a back alley. This could be a mistake or indicate that The Sacrifice was to consist of four parts.
  • The empty grocery store entered from the warehouse in the back will have its door become a part of the wall as scenery when you go across the street from the store, blocking off the ability trying to hide in the safe room. This is similar to what is done in the finale at Dark Carnival when the shutter door closes itself after the finale begins.
  • CEDA Workers Infected show up in the Port Finale of The Sacrifice, but not in The Passing, despite the fact that they take place in the same location.
  • The finale is similar to the finale of Crash Course, where the Survivors have to start up a generator to escape and then restart the generator again since it fails during the second wave of horde attacks.
  • If you reach the finale in the mutation Lone Gunman or Last Man on Earth, you still have to leave the bridge and restart the generator. Luckily, there is no need to retry the level.
  • This part of The Sacrifice has 7-8 Tanks (7 if one doesn't spawn before you reach the destination), so caution should be advised, as this will vary from 21000-64000 total Tank health.
  • There is a bug on this map where even if all Survivors are alive and on the bridge and/or if someone gets incapacitated, the failure message will pop up and the turn or game ends.
  • The finale has extensive lines of varying dialogs for each character participating in or witnessing the act of sacrifice. However, these lines are not used in single player.
  • When the finale is completed and the bridge is raised, Common Infected will always attack a set spot and not the actual sacrificing survivor unless they are their target before the resulting ending. This can result in situations like them completely ignoring nearer survivors that weren't on the bridge or attempting to attack the air.
  • This map seems to present an unresolved canon conflict regarding Louis' injured leg. During finale gameplay Louis' character is uninjured, yet Louis is definitively incapacitated by a severe leg wound in the chronologically valid storyline set out in The Sacrifice DLC and in the L4D2 The Passing campaign. However, it is strongly suggested by the comic that the in-game story is abridged for the sake of not intruding on the gameplay, with the comic portraying the actual canon events of the plot (in which Louis' leg is injured by a Witch).
  • Strangely, if there are Tanks within the near vicinity of the Survivor who restarted the generator, those Tanks can die when that Survivor becomes incapacitated. This is due to the fact that once a finale ends, everything classified as a player including AI tanks are frozen in place. When they can't get to the survivors, Tanks are programmed to fall over and die after some time. The fact that the Common Infected continue to attack the fallen survivor while the Tanks don't, may be an oversight.
  • Although one of the Survivor sacrificed himself/herself in the Left 4 Dead: Survivors version of the map, the game will say "The Survivors have escaped!" Instead of "In Memory of (Player/Character name)".
