Set L4D1 survivors on all official campaigns

if absent, the game uses L4D2 survivors

"survivor_set", decides which set of survivors should be used. 1=L4D1, 2=L4D2
so "survivor_set" "1" for L4D1 survivors
"survivor_set" "2" for L4D2 survivors

@LP-PADICIλ create a root folder copy the missions file folder for each campaign, the place the survivor set 1 section in each mission file, it's simple

another way is modify addonlist.txt located in <path-to-game>\left4dead2 and move the mod over every other mods

it should work if loaded before the campaigns (easiest way to achieve this is sub it first)

well you can just make a mod like mine but with every mission files from custom campaigns

You are genuinely a godsend!

It took me some trial and error and tutorial hunting, but I figured out how to remake VPKs with the new survivor sets like you mentioned, and it works like a charm! Unfortunately, that only solves the issue for myself and not others, so it's a partial measure, but it's better than nothing!

Now, to try and figure out how to apply it to every campaign with one 'simple' plugin... I don't think people would appreciate me reuploading their entire campaigns with just changed survivors. :p

I also suggest to read this: https://developer.valvesoftware.com/wiki/L4D2_Mission_Files

in the text files there's the option "survivor_set" "1", it's what forces L4D1 survivors, if absent or set to 2 the game will use L4D2 survivors

the mod's vpk file, you can extract it and than inside mission folder there's a text file, you can try by extracting this mod and you will find 14 text files (Valve's campaigns)
