Likely old news to some, but straight from the horse's mouth (for values of "horse" which equal "WotC") -- "In this special PAX East live D&D game, we switched things up a bit by having Chris Perkins play while Mike Krahulik and Patrick Rothfuss take a turn in the Dungeon Master's chair! After returning from the Underdark, the heroes of Acquisitions Incorporated find themselves with some free time on their hands, and we take a closer look at what goes on in the office and in their home lives. You can download Mike and Patrick's adventures for free right now from the Dungeon Masters Guild!"
