Graphic and sound mod for Left 4 Dead ver. 1.1 addon

This is an update of my mod (https://www.moddb.com/games/left-4-dead/addons/graphic-and-sound-mod-for-left-4-dead)

What's new on the spec sheet: the rate of fire of weapons has been changed in the direction of real samples, I redid the sounds of all weapons to make them more realistic has also been changed. The music and the main menu of the game were replaced. Ammunition for survivors has also been replaced, as well as monsters have been transferred from l4d2, you can all remove disabling the addon in the addons folder.
Many minor improvements and fixes have been made, especially with regard to sound bugs, now their number has been reduced to a minimum (I personally haven’t seen them, but I don’t know how it will be with you).

Is it necessary to install an update? - Yes, because a lot of fixes and changes for the better were implemented in it. Do I need to install this modification over the old version, provided that I did not install the old one? - No, it's not necessary, the new version of the mod is independent and includes everything you need, you shouldn't add even more unnecessary rubbish to yourself).

To install, you need to unpack the contents of the files to, for example, "D:\Games\left 4 dead\left4dead"
