Gas Powered Games' sci-fi strategy title released in March, features huge mechs, spider robots and other mechanised units and is getting a big boost with the ' Infinite War Battle Pack', due to stomp onto the Xbox Live Marketplace later today. Not for Supreme Commander 2 though, which has heralded the coming of its DLC with no less than three trailers and ten new screenshots. Sometimes the arrival of new downloadable content is accompanied by a trailer, maybe a few screens and some details.
