The war between the loyalists and the rebels within the TEC, Advent and Vasari continues within the depths of Trader Space. Yet, this sector of the galaxy has far more worlds and far more history than any of the factions are aware. Survival forces each to expand into the unknown, discovering worlds of hazard, wealth, risk, and mystery. Most ominously, the Trader factions have been loathe to expand to these worlds due to the dark myths that surround them.

The Next Installment to the Award-Winning RTS.

While many were hopeful that diplomacy would finally end the war, differing opinions on what should be done, along with the depleted power of the controlling factions, has led to a splintering of the groups involved.

The loyalist members of the Trader Emergency Coalition adopt a policy of isolation, focusing on enhanced defenses to ride out the rest of the war. Those who rebel against the coalition take on a purely militant view, coming to the opinion that the only way to bring peace is by ultimately crushing all who oppose them - especially xenos.

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).
