This is a newly remastered version of the unfinished campaign, The Undead Zone, posted with permission from one of the remaining members of the campaign's original developer team, NoPixelLeftBehind.

The campaign was originally a tie in to an indie horror film whose kickstarter never really got off the ground. Once the kickstarter fell through, development of the campaign also stalled in its final stages. The main objective of this release is to finish up the campaign with better optimization, polish, bugfixes, and versus balancing.

NOTE: This campaign uses custom sounds provided in a separate content pack which is included in this collection. Make sure that you also subscribe to the content pack to avoid any incompatibility issues with servers and have functioning sound.

The original campaign can still be found here. Note that the remastered version is meant to be installed as a stand-alone and having it installed at the same time as the original could lead to incompatibility issues.

The survivors' rescue chopper crash-lands somewhere in the desert outside of San Eden military base, a curious local hotspot for The Infection. In order to escape the desert and get back to safety, the survivors will have to make their way to a military outpost on the edge of the desert. To get there, they snake their way through an abandoned mine shaft, a ghost town, across desert dunes, and into the depths of San Eden base, which holds secrets as to how The Infection first broke out.

• Updated the campaign to accommodate changes from The Last Stand update.
  
• Improved the color correction to create more naturalistic lighting and color instead of the harsh oranges and yellows of the original.
  
• Time of day now cycles from afternoon to late at night, with proper HDR lighting and fixed tonemaps.
  
• Cleaned up and converted complex geometry into func_details.
  
• Boss spawns are now controlled by a custom vscript rather than by the Director, allowing for more consistency and control over where/when witches & tanks can spawn, while still being consistent between rounds of versus.
  
• Fixed broken infected ladders and added new ones.
  
• Adjusted weapon and item spawn amounts/locations for more balanced versus gameplay.
  
• Improved event and finale scripts for more balanced and consistent horde.
