I understood what was the matter. You cannot have Half Life 2 turned on. For everything to work correctly, you only need episodes 1 and 2

@diza.
Do you have both HL2 Episodes mounted?

i still have error models but i installed all things

The HL2 Zombies are the default enemies so you'll atleast need those.
The Antlions are not required unless you want to fight them.

so do I really need the antlions or the hl2 zombies?

@DarkSide360

If you want to fight different enemies then you'll need to follow the steps in the "How to change enemy setup" section
Aside from that, no setup is required.

Do I have to set things up for playing this configure?

And fix the lua error

AddCLuaFile: Couldn't find'autorun/bchlcic.lua'
1. unknown - lua/autorun/bchlcic_convars.lua:77

Hello, can you fix the bug with points when you kill zombies and an NPC drops 10 points from him.

do i really need the hla antlion or is it just a suggestion

@An average Beanmann

No worries! Looking forward to it Mate!

I made a mistake when adding the new grenade and satchel pickups, this will be fixed later today.

I've been getting a couple of errors on here for some reason. Not entirely sure why, but I'm not subscribed to anything but the map collection and Infected's content.

I've also tried validating files, and no luck there either. Not really sure what to do now lol

@upset

Thank you for letting me know about that, I'll update the map so it doesn't replace sh_music.lua sometime today.

Whoa, I didn't know adding mapscripts is possible by that way. Nice work! One note though: don't use and replace sh_music.lua, you can add your music tracks in map script itself. Like this: https://pastebin.com/gnKg9DZ8
