-FileA1 [(001)_CodTarkov_FileA_BrutalDOOM.pk3]
The game will start with "Sergeant_Mark_IV's Brutal DOOM (v21)" applied. Basically, this COD MOD is designed with this version in mind. Can be combined with most custom map mods.
However, it may not be compatible with newer custom map mods that include more advanced changes, so in that case, please use "Vanilla DOOM".
