@Mesozoic Gamer , start a map on Singleplayer, & then check in ".../Left 4 Dead 2/left4dead2/ems/". A folder with the name similar to this mod will be there, & the cfg file is inside the folder.

Where exactly is the config file? Trying to search within L4D2's overall folder and I just can't locate it unless the search bar is just liking to fail.

@L_M , yes. This works on any acid.

im using ka boomer that after kill it cause spit after that, it is work with this mod?

@kurochama works well, ty

@Kали , I just updated & added "acid_slowdown" feature. You can give a try.

@kurochama ty

@Shunyang , this one: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=579410433

what map did u use on your preview?

oh wow I've been waiting for a mod like this. thank you!!

@Kали , probably I can add the acid slowdown as the new feature later.

@kurochama Oh, its because the other mod is not working for me. An alternative would be good, even better with a configuration file

@M1Y4K0 , you can try "Melee Sharpshooting" for long-ranged melee attack.

@Kали , I think there's already a mod for that, but I forget who the author is. Probably the author is RF or Shadowysn.

could you add an "acid slowdown" feature?

oh awesome! thank you so much for your hard work @kurochama

I always assumed canonically the acid still hurts other zombies, they're just too angry to give a shit.

This mod is a good addition; the acid feels more real than just an artificial difficulty for survivors.

It'd make sense it also corrodes infected and nearby objects.
My only suggestion is an EMS setting to change the range, because 250 is quite big and the infected (mostly noticeable from the Witch due to her pain sounds from my testing) take damage despite not being inside the acid. They can be somewhat far and they'll still take damage.
