(Tutorial/How to) Add Slow Zombies to DayZ


Recommended Posts

I noticed that there are tons of slow zombie servers for Epoch/Overpoch including the Origins addition but very few for DayZ. I think there's only about 3. I searched around the good old inner web and found nothing released or instructions how to add slow zeds to regular DayZ so that's why I'm doing this one. It's pretty simple and should only take you a couple of minutes.


Tools needed:

PBO extracter (I use PBO manager)

Notepad ++


PBO's needed:

Mission PBO

dayz_code (should be found in (C:)/Program Files (x86)/Steam/SteamApps/common/Arma 2 OA/@Dayz)


dayz_code files needed:



complies.sqf (you do not need this if you already have a custom compiles)




1. Create a new folder on your desktop.

2. Copy dayz_code to that newly created folder and extract it.

3. In the compile folder, you will find zombie_generate.sqf. Copy that to your desktop.

4. In the system folder you will find zombie_agent.fsm. Copy that to your desktop.

5. In the init folder you will find compiles.sqf. Copy that to your desktop.

6. Using notepad++ open zombie_generate.sqf and find

_id = [_position,_agent] execFSM "\z\AddOns\dayz_code\system\zombie_agent.fsm";

Change that to

_id = [_position,_agent] execFSM "mods\slow_zeds\zombie_agent.fsm";

7. Using notepad++ open zombie_agent.fsm and find

"_agent forceSpeed (_agent getVariable [""speedLimit"", 3]);" \n

Change that to

"_agent forceSpeed 2;" \n

Steps 8, 9, and 10 can be skipped if you already have a custom compiles.


8. Unpack your mission PBO (dayz_1.chernarus) and using notepad++ open the init.sqf and find

call compile preprocessFileLineNumbers "\z\addons\dayz_code\init\compiles.sqf";

Change that to

call compile preprocessFileLineNumbers "mods\init\compiles.sqf";

9. In the root of your mission PBO, create a folder called mods.

10. Inside the mods folder create a new folder called init and place the compiles.sqf in that folder.

11. Open the compiles.sqf and find

zombie_generate = compile preprocessFileLineNumbers "\z\addons\dayz_code\compile\zombie_generate.sqf";

Change that to

zombie_generate = compile preprocessFileLineNumbers "mods\slow_zeds\zombie_generate.sqf";

12. Inside the mods folder create a folder called slow_zeds and place the zombie_agent.fsm and zombie_generate.sqf in that folder.

13. Repack your mission PBO and upload it to the server and enjoy the slow moving Zeds!
