Installing Left 4 Dead Mods - The Easy Way
16,316
Modding Left 4 Dead isn't easy, and neither is installing the mods
So, have you ever wanted to install a mod that you really REALLY liked, but to find out you couldn't get it working in Left 4 Dead 1? Well, today I am going to teach you how to install mods into Left 4 Dead and make Left 4 Dead more user friendly to mods (to a point)
Step 1: Unpacking the Main VPK
Now, this step kinda requires many steps, but it's easy once you know what you're doing.

Step 1.1:
Download GCFScape, you will need this to even extract the VPK.

Step 1.2:
Open up the VPK "Pak01_Dir.VPK" found in your "Left 4 Dead/left4dead" (which is found in "Steam/SteamApps/Common")
Step 1.3:
Extract it into your Left 4 Dead folder "left4dead"
Step 1.4:
Exit out of the VPK and rename it from "Pak01_Dir" to something else, like: "Pak01_Dira"

If you're in need of hard drive space, delete all of the VPK files found in the root. We won't be overwriting any files in the "left4dead" folder.
Step 2: Making a mod folder for Left 4 Dead
This step also has more than one step, but less than the top one.

Step 2.1:
Make a "left4dead_Mods" folder in the root where your "left4dead" and "left4dead_dlc3" folder sits.
(Disclaimer: There's a lot of language folders in the directory of Left 4 Dead, I hid them so you can see the main folders.)
Step 2.2:
Go into the GameInfo.txt inside of "left4dead" and add in "Game				left4dead_mods" under "SearchPaths"
Step 3: Installing a Mod
Obviously, since you just made a mods folder, it's going to be empty, like this:
But obviously, you're gonna install mods.

As an example, I'm going to install a recent port I did of the Aftermath Zoey.
Step 4: Testing it
Now that you've installed the mod, it's time to test if everything is working fine.

So, now it's time to launch up Left 4 Dead!
Step 5 (only if the mod didn't work): Finding out what went wrong
Sometimes stuff may break, so here's somethings to look into

Addons folder VPKs:
I haven't tested if these work with this method, if it doesn't, just move it over to the "left4dead" folder or unpack it into the "left4dead_mods" folder.

Forgot to remove Pak01_Dir:
Check to be sure you renamed Pak01_Dir or removed it with the rest of the VPKs.

Renamed files:
Now, a lot of mods provide renamed files to edit the Pak01_Dir.VPK, no idea if these renames will cause any issues within this method, if it does, you may need to hex edit their names back to normal.

why is it so complicated for l4d 1 but not l4d 2, all you have to do is copy the file you download and paste it in your add ons folder for l4d 2. also this is what i did for l4d 1 when i downloaded the dam it map and that worked just like in l4d 2, why are skins and other stuff different ?

surely you can exctract content from all vpk files and write sv_consistency 0 in console, which not required sv_cheats 1, for possibility launch campaign, but in this case are possible play only on local server

You're likely running a pirated version of Left 4 Dead.

Did you do The "gameinfo.txt" Part? If no then you must do it.
