Take the battle for galactic supremacy to its ultimate level in Sins of a Solar Empire: Rebellion – a standalone RT4X game that combines the tactics of real-time strategy with the depth of the 4X genre (eXplore, eXpand, eXploit, eXterminate).
Published by Stardock Entertainment, the game pits loyalist members of the Trader Emergency Coalition, who adopt a policy of isolation, against rebels who take on a purely militant view.
