I don't know if this is the right place for this but I figured I might as well. I'm trying to install a mod into my Half Life 2 game to replace alyx with the combine assassin model someone made. The only problem is the way to install it. Everywhere I've looked, people say to put the folders in the Models folder and the Materials folder...I didn't have either of those files when I opened the directory. What's going on? The game runs fine so the models are obviously there but I don't know where they are. What am I supposed to do?
