"Find a rural holdout being used by the military to rescue survivors."

Blood Harvest is the fifth and final (on first release, the fourth) campaign in Left 4 Dead. After their rescue aircraft is lost, the Survivors hide out in a forest until learning of a nearby military outpost located at a barricaded farmhouse. They set off through the forest and follow a series of train tracks until entering a military controlled area only to discover the outpost is abandoned. A radio call to the army base at Millhaven triggers the finale and they must hold out until an armored personnel carrier arrives.

The subsequent DLC comic The Sacrifice and campaign of the same name pick up after this point and conclude the entire game. The survivors are betrayed by the military command at Millhaven which is itself out of touch with its own high command. This experience colors their subsequent attitudes and creates a stark contrast to their hopes at the start of Blood Harvest.

Along with the other Left 4 Dead campaigns, Blood Harvest was ported over to Left 4 Dead 2 on August 5th, 2011 after 60,000 players acquired the Connecting Fight achievement for Left 4 Dead 2's Dead Air. As with all the ports, various detail-changes were made to weapons, enemies, pathways, environmental elements and combat sequences.

Below is a complete list of video walkthroughs of the 5 levels:

Official description[]

Zombies lurk behind every tree, over every hilltop and behind every shadow in this terrifying moonlit search for a rumored evacuation zone to the north: several acres of back-country farmland taken over by the military to get the last of humanity out of Ground Zero. Plunge through pitch-black forests, stumble blindly through fields of swaying corn, and take aim at the silhouettes leaping at you from the darkness—all towards finding a hold-out that might already have been abandoned to the horde.[1]


Writing on the wall on Blood Harvest

Candy Mountain is only a few of the labeled regions; one other is Red Ridge Lake at the lower mid-left-hand side

Safe room graffiti in this campaign is the usual mixed bag of content and literary communication values.

Of note are those inscriptions urging survivors to get to a safe zone by following "the train tracks."

Although not graffiti, the Survivors encounter a number of official signs bluntly instructing members of the general public as to how to behave when approaching a military-controlled facility.

One says: "Keep your hands above your head in the field at all times or you will be shot on sight!" while another says:

  1. Do not run at military personnel.
  2. Do not ignore personnel when they address you.
  3. Do not make any violent or sudden movements.

Similar signs are also seen when arriving at the Bridge in Left 4 Dead 2.

The map on the farmhouse wall in the radio room is labeled Candy Mountain.


As revealed by a park sign at the starting location, this campaign takes place in and around Allegheny National Forest in Western Pennsylvania, a couple hours' drive from the city of Pittsburgh. The comic The Sacrifice confirms this with a note locating Evacuation Outpost Echo in upstate Pennsylvania. Based on dialog and an opening scene complete with sleeping bags and campfire of burning dollar bills, the Survivors have been hiding out in the forest after their Dead Air C130 escape airplane was lost. A character in voice-over announces the existence of a military safe zone to the north and all they need to do to get there is to follow the train tracks.

Behind the Scenes[]

Beta versions of Blood Harvest were much greener and brighter than the final version. In addition, there is no fog, making the sky much more visible.

Some chapters of this campaign were also different:

  • 1) The Hilltop
  • 2) The Train Tunnel
  • 3) The Bridge
  • 4) The Barn
  • 5) The Cornfield[2]


  • Zoey's stance on the campaign poster is similar to that held for No Mercy, minus the extra hand and her standing instead of crouching.
  • The top right corner of this poster of this campaign can be seen on Dark Carnival's poster.
  • This is the only campaign in Left 4 Dead which does not include a Minigun.
  • Although the official description uses the term "moonlit", the campaign seems to begin at dawn.
  • It is hinted that the Survivors camped in the woods since three sleeping bags are seen at the campaign's start and Francis makes an acid remark about how he cannot believe that people go camping "for fun."
  • Bill and Francis have the most campaign-specific lines. Louis has only one line of this type and Zoey none.
  • In the opening scene at the campsite, the signboard for Allegheny National Forest features small, hard to read print near the bottom which reads: "This forest is not for the faint of heart. Enter at your own risk. Not responsible for lost or dead friends. Reserve your camping spot now! I'm warning you. Stay away if you know whats good for you. You'll regret it. Yes you will. Yep."
    • This phrase also appears on the bottom of the Allegheny Forest sign in The Terminal.
  • Since the release of The Sacrifice comic, it is now apparent that Blood Harvest is the fifth of six campaigns in total. After "rescue" by the military, the Survivors are imprisoned at Millhaven. Their escape sets up The Sacrifice campaign.
  • Pittsburgh (and its surrounding region) is famous for providing the settings to many films such as Night of the Living Dead and Dawn of the Dead.
  • The semaphore signals by the bridge in the third chapter flash between green and red without the signal arm moving. This cannot happen because these colors are filters in the signal arm.
  • In this campaign in Left 4 Dead 2, as well as in Crash Course and Death Toll, no Uncommon Infected spawn during play.
  • There was an exploit in the Farmhouse Finale which prevented the survivor from getting damaged by staying by a dryer and a washer (It's currently unknown if any Special Infected could still target them) though it has been patched.
  • The survivor’s stances all match up to their character select pictures as well as the pictures used at the end of a chapter when the leaderboard is shown.
