  • Omen is defined as an event regarded as a portent of good or evil.
  • The original name planned for this chapter was "Evacuate".
  • It requires 3 maps to run this chapter. This is also the first chapter in Zombie Scenario to feature multiple maps.
  • This is the first Zombie Scenario map to introduce the Parkour Zombie.
  • Players will spot some zombies from Zombie 4: Darkness behind a blue door at the spawn zone. Once the helicopter has been destroyed, they will disappear.
  • Before the helicopter crash sequence, the players can hear a radio sound from Recoil mission of Condition Zero: Deleted Scenes:
    • "CnC, this is Red Tail 5. We are approaching the drop point. Area looks quiet."
    • After the Laser Wing attacks: "CnC, this is Red Tail 5! We have been hit and going down! Repeat! This is Red Tail...".
    • After crashing: "Come in! Any survivor members of Red Tail 5! Be advised, multiple hostiles are moving in to your position! Ranger 3 Bravo Team is pushed to your position. Move away from the crash site and run with Bravo Team immediately!"
  • The promotion art shows Jennifer wielding a UTS-15 along with a few soldiers supporting with several weapons such as M4A1, K3 and Desert Eagle.
  • This map resembled The Parish campaign from Left 4 Dead 2, another Valve's game. The third mini-map's structures actually resembled The Last of Us, an action-adventure survival horror video game.
  • In early releases, there were two bugs that were later addressed and fixed. They are:
    • Sometimes, Laser Wing will get stuck in the place between a tree and a skyscraper. Players can exploit this bug to defeat him easily.
    • After going to another map the player's appearance will be set to a default faction's model regardless of the character previously chosen. Also, all buff items such as the tattoos or costumes won't have any effect at all.
  • The background musics in this chapter are similar to the ones in Toxicity. However, they are now clearer because used in mp3 format and adjustable volume in the audio setting. Before this, they were using wav format in Toxicity. The used musics are taken from Alamo, Pipe Dream and Recoil missions from Counter-Strike: Condition Zero Deleted Scenes.
  • There is an obstacle that needs the player to push it in order to proceed. The player can press the E + W buttons to push it in a very fast way. This is a known bug that already present in Half-Life when the player pushes and pulls boxes.
