Summer storms are a thing where I live. And it's getting stormy out on the fields of Warmachine as well. Privateer Press has posted up their Dev Notes for the latest Dynamic Update that's all about the Cygnar faction and the various storm-units therein.
From the update:
This dynamic update will focus on Storm Division and Cygnar warjacks. There were no changes made to theme lists as a result of this dynamic update.
