This collection improves textures and reanimates items and weapons. A strong drop in fps was not noticed and everything was selected so that there were no conflicts and repetitive mods.
Tank Attack and Concert changed to tracks from metal band Dethklok, as well as escape music changed to The Gears track - https://www.youtube.com/watch?v=czEMC8RHvnk,and replaced the music at the beginning of the Dark Carnival campaign. Just click on "Subscribe to all" and enjoy the game that pleases the eye and every action in it creeps out. Absolutely all textures have been changed, models of survivors and special infected are also replaced. In this collection, I made a Mix from common infected,now the apocalypse looks more realistic and each map has Swat, Ceda, and Fallen, as well as models of soldiers and police. The sounds of the weapons have been replaced with more realistic sounds, and when an AWP or Scout rifle is fired, you can hear the cartridge case fly out, and when you reload the shotgun, how the shot is inserted is fully conveyed, and so on with each weapon.
Models of firearms are made in HD and use animation by many famous modders. This collection also affects the AI, both survivors and the infected, now they are smarter and now ordinary bots can use grenades and transfer items to you, including first-aid kits.
Enjoy your game and have a nice day!
