Have you ever wanted to create a half life 2 mod? Well if you have, now you can. With this base mod. Every thing is set up for you! All you have to do is put it in the source mods folder. Restart steam, then take off! Obviously you have to add your own custom content like, maps, materials, sounds, and codes. But Examples are already there! And it should be fairly straightforward! There is a WhatToDoHere.txt in every folder explaining what it is for the most part.
