Randall and friends have been busy over at Catalyst Game Labs. They've got a new sourcebook for Shadowrun available in pdf (with print versions available for pre-order) and a new adventure that works with it. I did say that they'd been busy.
The sourcebook is Market Panic. It gives you a look at the Big Ten corporations in the Shadowrun world. Each one looking to get ahead in a cutthroat world where they can gain and lose billions of nuyen in a moment's notice. The adventure is Serrated Edge and fits in with the Market Panic book, taking you to the streets of Denver.
