The original title by
Activision which was followed with Dark Reign:
Rise of the Shadowhand and recently
Dark Reign 2.
The game pits a battle between the freedom loving fighters, freedom guard, and the stereotypical galactic empire, oppressive type bad guy, the Imperium. The game had 25 single player missions (12 for Freedom Guard and 12 for Imperium plus one generic final level) that were impossibly difficult. It took the most skilled of Real Time Strategists to defeat this game, which greatly lengthened its longevity.
The multiplayer engine was fairly poor, but this was rectified in the expansion Dark Reign: Rise of the Shadowhand.
