Download GCFscape, open the Left 4 Dead 2 game files, navigate to the addons/workshop/ folder. Look for this mod, open the .vpk in GCFscape. Drag and drop the root folder to copy it onto your drive. Edit values in the mod to your liking (what you want to do is very easy number changes). Rename the root folder and drag and drop it onto the bin/vpk.exe executable in the game files. Now, drop it in the addons folder. Done.

Ive never modded anything so il probably have to find someone to do it for me unless you give me a basic quide, i tried opening the source code but its encrypted

I would but I'm lazy. You have my permission to take this specific mod and edit whatever you want with it.

is it okay if you make a version with 250 zombie limit and 200 mob size? itll probably be roughly the same experience with half of the lag

Really fun otherwise when my fps isnt below 20 xd

I was trying to figure something out how the cvars work? can a cvar inside a vpk file override the sv cheats 1? In which I mean you dont have to enter sv_cheats 1 to execute the z_etc. cvars? Or maybe thats why this is was made to a mutation as the coop game mode does not support cvars that has a dependency on sv_cheats 1? Thanks for answering...

While running this mod I also noticed increased spawn rates for hordes on regular levels too.

This mod somehow breaks The Passing finale, and possibly other gascan finales too. It causes never-ending hordes to spawn during the finale on a local server, even if playing campaign/realism

Dear God Almighty OhMyBeJesus for a Mutation like this is crazy the amount of zombies wave after wave is 500 making my computer lag and framerate starts to drop below 30fps at the same time this almost does look like World War Z game

i love it.

Jesus loves you! I warn you of your sins, repent and believe the Gospel!

You can download the Admin System mod and kill all the bots when you spawn in. Or you can start the map in console using, "map {mapnamehere} neverend" and then typing "nb_delete_all Survivor" in console

Great mod! Is there a way to play with no bots?

9/10 Not enough zombies. -Nick

It's unfortunate, nothing I could do without getting rid of the zombie count.

Holy SHIT this is a REAL Apocalypse but a real DROP of FPS :(

this is pretty fucking cool good job

Thanks for the positive feedback!

This is how L4D2 should be in reallism. Great mod, mate!
