This is my first work that I first made for myself, but still decided to put it in the public domain. In fact, it really motivated me to start doing 3d graphics.
To install:
1. In the folder with the game, create a folder "portal2_dlc3" in which to drop the file "pack01_dir"
2.Register in the console "snd_rebuildaudiocache;snd_updateaudiocache;exit".
i really wanna install it!
