Gamespot takes it's first look at the upcoming Entrenchment expansion for Sins of a Solar Empire.  They also have an exclusive game play video showing Entrenchment "in action".

Technology has also advanced, and Entrenchment will introduce a new superunit, the star base, which Iron Clad says will radically alter Sins strategy and gameplay."
