Today I'm talking to Obsidian, host of the Abyssal Speedmapping  Sessions, the MAYhem community project series, as well as a number of  other community projects, creator of Maskimxul, Countdown to Extinction, and Candlemass, to name just a few of their projects over the years.   

We talk about creating atmosphere in Doom wads, features Obsidian would  like to see used more, and how to run good community projects.
