From the announcement:
When venturing in Limbo at the edge of the galaxy, scouts found a new form of energy: Titanium. First experiments showed it could push back the frontiers of technology, and even open new horizons for human capabilities. This news was more than enough to stir up the greed of humankind’s greatest factions. Each has sent fleets to take over nearby planets where Titanium is abundant – and even seems to be in constant expansion. From that point on, armed conflicts were bound to happen, and this war will be settled only by controlling the Titanium deposits...
Purchase buildings to master new technologies and increase your earnings. Buy units to expand your fleet and enhance your spaceships with powerful equipments. Explore the edge of the galaxy and adjust your tactics to seize control of new planets rich in Titanium.
