Reactive Zombies for Project Zomboid (v41.x)

Zombie attributes and behavior change with your actions. Too aggressive? Zombies become stronger and tougher. Too passive? They get smarter.

After months of slaying zombie after zombie, you may feel like they're too weak, they don't respond to your actions, they're just walking/sprinting things wanting to eat your brain, but that's it. They won't change, their strength is the same at day 1 and day 365. If they are about to die, they behave the same as if nothing is happening. Well, time to change all that!.

Zombie attributes and behavior are now dynamic. Long gone are the days where zombies were just the same on day 1 and after 6 months. First, let me explain what mechanics the mod use for zombie attributes and behavior to change with time:

• Demolisher Mode: If a player isn't seen by zombies in a day, make the zombies more destructive (these stats revert a stage if the player is seen by zombies again);
• Last Resort: If a zombie is about to die, there's a chance it becomes stronger and faster, as a last resort to try to survive.
  
  • Last Resort can happen if a hit zombie's HP is below 100;
  • Base probability is 1%;
  • Probability increases if:
    
    • Chasing Zombies: If chased by 3 or less zombies, increase probability by 1%-2%-3% as zombies chasing goes down to 1;
    • Player Health: Increase chance by 2% for every 25% HP the player loses (up to 6%, 75% max HP loss);
    • Player Weapon: If the player hit the zombie with a ranged weapon, increase chance by 2%;
    • Player Wounds: Every unbandaged wound increases chance by 3% (12% max), if it's bandaged, it's 1% (4% max).
  • After a last resort zombie dies, it emmits a sounds with a radius up to 50 tiles, attracting other zombies, so be careful!
• Player Playstyle:
  
  • Zombies can become stronger on a X:1 kills/days survived ratio (customizable in Sandbox Settings);
  • Zombies can become tougher on a X:1 kills/days survived ratio (customizable in Sandbox Settings).
• Time elapsed:
  
  • If enabled, each day there's a probability that zombie fire resistance increases to a maximum (customizable in Sandbox Settings). Zombies take x4 damage to fire at the start of the game;
  • If enabled, each day there's a probability that zombie mortality increases, making zombification faster (customizable in Sandbox Settings);
• Time of Day: At night, zombies see less;
• Weather: Zombies may be more blind, slower and less perceptive during stormy, foggy, rainy and snowy days.

Every zombie attribute (strength, toughness, cognition, etc.) and behavior depends on these mechanics.
