Hegemonia: Legions of Iron
Hegemonia: Legions of Iron is a 3D real-time strategy game made by Digital Reality and is similar in many respects to Homeworld and Digital Reality's previous game, Imperium Galactica II.
Storyline
Hegemonia takes place in the distant future where humanity has colonized the solar system and tensions are high between the World Government of Earth and colonial Mars. A summit on Earths moon is planned to ease tensions, but the Martian representatives shuttle is destroyed en-route by a third, currently unknown party. The two sides blame each other and this one event sparks off the civil war between the colonists and Earth.
You can side with Captain Jack Garner of Earth to quell the colonial uprising, or join Captain Nilea Cortilliari and the Martian colonists on their campaign for independence.
Once the outcome of the civil war is decided, be it Earth or Mars, humanity unites under the new Unified Government and forms the Legions of Iron, its vanguard of expansion into the unknown.
As the human race expands outward from Sol, mysteries are solved and more new ones are created as they encounter new worlds and alien civilizations.
