Set in the immediate aftermath of the zombie apocalypse, Left 4 Dead's survival co-op mode lets up to four players blast a path through the swarming zombie hordes and terrifying mutant monsters. Guide your survivors across the rooftops of an abandoned metropolis, through rural ghost towns and pitch-black forests in your quest to escape a devastated Ground Zero crawling with infected enemies.

Get the NEW v1.1 (which has been updated for 'The Sacrifice' DLC) in your choice of format at one of the following links:

File Replacement format:


VPK Add-on format:

(If you choose the VPK version, also get the small texture fix for it here:
otherwise you will be missing a few of the mod's poster textures.)

This mod is great! The sound replacements for the zombies remind me a lot of 28 days later,
which is AWESOME!
(Heck, it even has edited versions of the 28 days later sound track, also awesome.)

Thank you for your interest. I had initially planned to release a vpk version, and even had a couple of kind l4d2 modder folks trying to help me out with making one...but they discovered that, unfortunately, L4D2 does not support sound mod add-ons at the moment. If an update changes this, I may release a vpk version, though it's fairly easy to manually install it as-is.

the trick is, you must apply the snd_rebuildaudiocache command in console after you added the VPK, and presto!

Thanks for this info, GJ! I'm guessing this solution would have to exclude the mod's replacement content for 'The Passing'? VPK downloaders would then be missing out on some cool stuff, then :(

GonzoJager Aug 19 2010, 10:46pm replied:

I think I found a solution to enable the sound in a VPK format, its a little unorthodox, but I reckon this will do until Valve comes up with a support for a more convenient way:
1, I separated the Passings sound files/folders ( left4dead2_dlc1 ) from the rest of the mod
2, renamed the sound folder left4dead2_dlc1 to pak02_dir
3, made a VPK out of it -> pak02_dir.vpk (no addoninfo)
4, copied this pak02_dir.vpk to the games's ...\left 4 dead 2\left4dead2_dlc1\ folder
5, It works! :D

Of course it's not as convenient as a real Addon VPK, eg. if you want to disable it you have to either delete the pak02_dir.vpk or move it, or maybe rename it.

I've already done that, ever since this great mod came out :)

for the basic game it's a fairly simple procedure, although this is a biggie (around 855MB - just the sounds) the system can handle it. one will have the luxury to turn it On and Off at will. I have yet to figure out a way to make vpks to the Passing DLC.

It's really easy, first just make a backup copy of your two original sound folders, (my mod's ReadMe tells you where they are), then open the mod you downloaded with WinRar or Winzip, and simply click & drag everything in it into your main directory (x:\Program Files\Left 4 Dead 2), choosing 'Yes' to overwrite.
Installing the custom textures is a little more involved, but if you want to only install the sounds, that's it!

Yes, that is correct GJ :)
Not sure what you mean by "the new VPK built-in sound chase". I was going to release v1.1 in much the same way as v1.0, (folder replacement structure), BUT since you thought of that brilliant work-around, would you be interested in helping me release a vpk version of it and be credited as such?

GonzoJager Sep 19 2010, 9:02am replied:

I'm sorry, somehow I always mix those 2 word up: I meant the sound cache - this update:

" Authoring Tools
- VPK files now support their own sound.cache file.
- Use the command "snd_buildsoundcachefordirectory " to create the sound.cache file that you should include when you create your vpk file. "

Sure, I'll be glad to help out if I can, but the credit should go to you, you're the one who done the hard part - I just merely fiddled with the files ;)

Cool, Thanks! I'd appreciate the help. For some reason, my vpk.exe only works with extracting files from add-ons, and does not work when trying to compile/create vpk's :p

That was still some clever fiddling! I'd still get credit for the mod itself, but you'd be credited for converting it to a vpk add-on :)

GonzoJager Sep 21 2010, 4:38am says:

Okay, I've made some neat zipped-in VPKs: one for the main game sound&music (765,5MB), one for The Passing DLC sound&music (100,3MB), and one for the Midnight Riders posters&props Skins (6MB)! Now all it needs is a place to upload them... :)

PS - about the sizes: I used 7zip, because it had the best results on shrinking down the files, plus its a free app.

After 'The Sacrifice' update, I personally did not experience any broken sound issues with the mod. I'm currently working on updating it to v1.1 to include new DLC replacements as well as some minor tweaks. There will be a vpk version of this available once this is completed.

I can't seem to get it to work properly. The gun sounds mostly work, and from what small 10 seconds worth of music that plays, it seems like the music is great, too. Unfortunately, when using this mod, 70% of the sounds are gone. Not sure what I did wrong :/

Hmm, that's a strange problem you're having. Have you tried the "snd_rebuildaudiocache" console command I mentioned in the mod's ReadMe?
Give that a go & then see if it works. If not, I'd recommend downloading it again & simply installing over what's already there, then repeating the "snd_rebuildaudiocache" console command. Hope that helps!
