Take a look at these in-game screenshots Stardock sent us for their upcoming expansion to their 2008 RTS: Sins of a Solar Empire. Sins of a Solar Empire: Rebellion adds subfactions to the game by splitting the existing factions into two: the loyalists and the rebels.
The time of Diplomacy is over. The length of the war and differing opinions on what should be done to bring the war to an end has led to a splintering of the groups involved. The controlling powers-that-be have depleted arsenals and seemed to have exhausted all efforts of diplomacy. Trapped in a stalemate, sub-factions have rebelled and broken off the main alignments. Rebellion is upon us.
Check out the screenshots below. More information on Rebellion can be found at www.sinsofasolarempire.com
