DESCRIPTION

This mod introduces the mechanic that behind any closed door could lurk infected zombies ready to ambush the player. It works with most vanilla buildings and modded buildings depending on how they are made. Even multi-level buildings. Your players will never open a door the same way again. Who knows what is on the other side...

  • Zombies will only spawn inside a room behind a closed door out of sight of any player.
  • every closed door has a potential to trigger the spawn
  • configurable spawn chance
  • designate safezones via config
  • excludes territories (if using expansion)
  • exclude specific buildings from spawning zombies
  • make spawning zombies exclusive to specific buildings
  • player and group door history ensures zombies will not spawn inside rooms recently cleared
  • allow specific zombies to spawn

UPDATED 6/23/25

*No changes to the config*

  • added vanilla territory support
  • check if player is in vehicle
  • now caches some results, like territory, safezone and vehicle check, and reads the cache until expired (saves resources)

Note: There are many factors that go into if an zombie will spawn. Having a spawn chance of 100% does not mean 100% of doors will spawn zombies. It means that when all the factors align and give a green light to spawn then there is a 100% chance the zombie will spawn.

REQUIREMENTS

  • Can be run as server or client mod
  • This is a spinoff of my Knock Knock AI mod. All requirements for Expansion should be removed. If I missed something let me know

FEEDBACK IS KING

Hey ho flying by the seat of my pants here and as such your feedback helps to make this a better mod. Find some buildings that cause issue? Let me know. Got a suggestion? Let me know. I have only used this mod on Chernarus but there is no reason it should not work on other maps - only poorly made buildings should be any issue.
