Seems to slow down the walking speed of the Charger as well (though the other Specials seem to remain unaffected).

depends what stats, but yes some like backup ammo count will cause conflict as they both change the same file
t_alex_v2 16 Feb @ 2:38pm 
mods that change weapon stats also conflict with this mod
Digital_Revenant 27 Nov, 2023 @ 10:25pm 
damn, that sucks
Blackcat12951  [author] 27 Nov, 2023 @ 10:13pm 
most likely both those mods alter one of the same files that this one does, gamemodes.txt, as thats one of the very few ways to ad cvars to the game to change stuff

I've had 2 mods (Increased fog and blue survivor names) conflict with this.
Digital_Revenant 27 Nov, 2023 @ 6:01pm 
Why does this conflict with mods that don't even do anything to the common infected?
Blackcat12951  [author] 13 Jul, 2023 @ 8:14pm 
no, as it changes the same file as this mod, so one will overwrite the other

works w/ "double or nothing" mod?

I only have all special infected with variants, complete population, complete population extended, and some mods that I don't need
Blackcat12951  [author] 23 Jan, 2023 @ 5:57pm 
it shouldn't be an issue, as far as what i know about how l4d2 handles mods
MaxFar 23 Jan, 2023 @ 2:18pm 
I just tried it alone, started some campaign and at least for my game it is working. I informed the others to also check indivudally. Maybe someone has not installed the correct mod. We have to investigate this issue. Last times, we played the mod, we did not start from the beginning but started where we left without the mod. Maybe that caused the issue? Is it necessary to play with the mod from the beginning? Thanks
Blackcat12951  [author] 23 Jan, 2023 @ 1:58pm 
this mod just reduces movement speed. as for it not working, are you playing on a local server? others have reported thats the best way to get it working in multiplayer
MaxFar 23 Jan, 2023 @ 12:10pm 
Hi, anything we can do to fix this issue? We restarted L4D2 also already and the mod is checked with all three players.
MaxFar 21 Jan, 2023 @ 1:03pm 
Hi Blackcat, we are currently playing with three friends and one bot your mod but it seems zombies are not really slowed down. The mod is activated on all players but zombies are still running. Does the mod not reduce the running zombies but instead slows down the reaction of the zombies? Greetings & Thanks
MaxFar 11 Jan, 2023 @ 3:55am 
@Blackcat12951: Thanks for clearing up. Good work with these mods. Thanks
Blackcat12951  [author] 10 Jan, 2023 @ 9:32pm 
This should be what you are looking for, yeah
MaxFar 10 Jan, 2023 @ 12:57pm 
Hiya, I'm looking for a Slow Zombies Mod but with Special Infected and Tank, so basically the main game but with 75% slowed down zombies. Is this the correct mod? Thanks & BR

DustyLucas Very sorry for the delay, here is your request.

Pyrokzx 17 Jun, 2019 @ 7:17am 
Thank you very much, but could you please maybe recreate this version still with special infected but make the zombies slowed by 60 percent instead ?
<Net> Fiend 18 May, 2019 @ 6:05pm 
That did the trick :D!

Thanks a bunch pal!?
Blackcat12951  [author] 17 May, 2019 @ 10:20pm 
after disabling this addon, restart l4d2 to ensure all changes are removed.
<Net> Fiend 17 May, 2019 @ 5:20pm 
Don't know if you're still alive, but here's my problem with this mod should you be breathing and able to reply.

I subbed to this mod and had a blast with it.

NOW I unsubbed cause I had my fill of it and now the common zombies are still behaving as it the mod is still installed. Do I just need to close the same and reopen it as normal or do I gotta do some software work?
Blackcat12951  [author] 20 Nov, 2018 @ 7:59pm 
If it is not working,it is most likely a conflict between addons. turn off any other addon that change bot behavior, backup ammo limits, cheat mods, changes to infected stats, then restart l4d2.
Kundra 20 Nov, 2018 @ 7:57pm 
doesnt work for me..
Blackcat12951  [author] 12 Nov, 2018 @ 8:59pm 
Sorry for the late reply. I had a look and that addon failed to work for me as well. I tried looking at the files and while the is no conflicting files, I am unable to open them. I can't think of any way to fix them not working together, perhaps the author of the other addon might have an idea. Alternatively you could try the other authors different version of the addon here https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=1380634664

I have found that this one works most of the time with the many other addons that I run.

Thank you so much, I was able to change the zombie speed and ammo amounts for the single player game.
But becuase you are more skilled at this than me, do you have any idea why this Bullet Tracer mod isn't working.

https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=492956591

when I manage my add-ons in the game I get no red conflicting files; however, the bullet tracers won't appear with the slow zombies mod. I tried to view the code for the Bullet Tracer mod but nearly everything is unreadble.
Blackcat12951  [author] 2 Nov, 2018 @ 9:36pm 
the main software needed for left 4 dead 2 modding is a vpk opener. all addons for l4d2 are stored inside a vpk file. the one i use is
http://nemesis.thewavelength.net/index.php?p=26
the much better notepad++ keeps everything in order and has great visual cues as to same words, what line you're on etc.
http://notepad-plus-plus.org/
this shows how to unpack and pack.
https://www.youtube.com/watch?v=P3ILjexx0cE

here is an example of one of my addons https://pastebin.com/nC69FCGp . please note you will have to alter the same lines on the scrpts for the finales as well so the changes are applied to the official finales.

the line you want to change is z_speed 250
(thats the default speed value above)

feel free to ask any more questions if you have them.

Also, for those looking to download the slow zombies mod: https://gtm.steamproxy.vip/profiles/76561198810902084/myworkshopfiles/?appid=550&browsefilter=mysubscriptions&p=5 is not compatible.
Bugget_Noxes 2 Nov, 2018 @ 7:02pm 
I love the mod; however, is there any easy way for me to edit the souce code? The zombies are just a little too slow for me.

TheCoolness 21 Jun, 2016 @ 9:06am 
thx for link

I feel bad for the creator, everyone's criticising the creator for it not working/asking the same questions over and over.
I've never had any problems with this specific mod and I use several nice mods.
Good job creator.
usabaker 3 Jan, 2016 @ 1:10pm 
this is bad, this makes all survivors say Go Go Go! And it gets very annoying It does make Zombies slow but it does that

Ah, thanks.
Blackcat12951  [author] 16 Apr, 2015 @ 5:27am 
its not a mutation, it will work automatically when enabled in the addons menu.
RAPTOR 9:48 16 Apr, 2015 @ 2:58am 
I tried to find it in mutations, and I couldn't find it. where should I be looking?
homiemcg 4 Mar, 2015 @ 4:02pm 
really usful 4 hard maps
Blackcat12951  [author] 10 Jan, 2015 @ 8:18pm 
yes, unfortunately all zombies are affected by the same line of code.
Devil of Brazos 10 Jan, 2015 @ 1:12pm 
are the special infected slow?
