Not much time left till it detonates... Remember, the goal is to escape!

  1. You can camp at certain areas and use high knockback weapons like TAR-21Double-barreled shotgun or Winchester M1887. However, make sure to reach the escape zone before it's too late.
  2. After 25 seconds, the first area to clear, you can camp and hold off the zombies. Use high damage and magazine weapons such as B mode of SKULL-3SKULL-11 or any Light Machine guns. Note this is only for a human player willing to sacrifice for the other human players to get a better chance to escape.
  3. Camp at a gate near to the door at the first obstacle and wait for all zombies to get down the stairs then start shooting them. Use any weapon with penetration ability to do this.
  4. Be careful about some humans that deliberately turn themselves into zombies for some reason such as getting [Cold Blooded] medal quickly or friendlies actions.
  5. Do not spam Flashbang as it will cause many players blinded, ended up being infected by a zombie. There is a chance you might get kicked out.
  6. It is always a good choice to leave the supply boxes that contain Vital Detectors and Ammo Supply to the campers.
  7. It is recommended to have more campers than the leading front as when humans have no campers, it'll have higher probability to be zombies.
  8. Always wait for the campers/covers at the boat so all the humans can escape.
  9. Be careful of some players performing bugs, teleporting to the finish area and deliberately escaping alone.
  10. Don't use Steyr Scout even though it is known for its speed increment. This is not just an escape, it needs teamwork to prevent being infected from zombies and successfully escape together.


  1. Focus on infecting leading humans since they can escape easily.
  2. Infect the campers to save your time from being slowed down. You can see the progress bar HUD to find camping humans.
  3. Avoid being killed by the collapsing crates in the first obstacle.
  4. Avoid humans spamming Flashbang.
