I am a level designer for the Source engine. I am currently working on a couple of mods, including the remake Black Ops:Source. Since I have been working with the Source engine for about 3 years now, I know most of the tricks and loopholes of level design. If you have any problems with hammer, let me know and I'll do my best to help you out.
The beta of the training map for the Wilson Chronicles. Its still in the beta stages. We're planning on having a cliff in the background, and a few buildings to the right. The dev texture will be replaced by a road texture as soon as I have some time to rotate the textures.
