Hammer Editor Development Group

We are a public Source Engine development community since October of 2017. We are composed of over 4,600 members with different skill sets and levels of experience, including level designers, 3D modelers, programmers, graphic designers, and niche developers, including skybox and soundscape artists. Every year we host several mapping contests where our members compete for a variety of prizes and hone their game development disciplines. There are a wide variety of resources available to our members in terms of support in level design including dedicated helpers, custom assets, and a knowledgeable base.
