That's a new trailer for Stardock's upcoming expansion to Sins of a Solar Empire. It'll bring jumbo-sized Titan ships and new faction choices to the outstanding 4X space strategy game. It'll also provide a much-needed graphical update to the four year-old title.
There are three reasons why I still boot up Sins of a Solar Empire: I get a dizzy thrill every time I zoom from an extreme close-up to a map overview (I call it the Supreme Commander effect), and I enjoy playing co-op in a universe so vast that I hardly ever encounter other human players. Also, I like telling people I've been playing "Sins of a Solar Empire" because it makes me feel cool.
In Sins of a Solar Empire: Trinity, you are the leader of a civilization embroiled in a galactic war, fighting for the survival of your entire race against relentless foes. Your success will depend entirely on your ability to manage your empire and command your vast fleets of starships to victory.
