GDN - In Blue Libra, the player commands the last remnants of a once proud civilization as they attempt to reclaim their home world of Tenerna from the ruthless Gardian Empire. To accomplish this, the player is given control of the Libra, a massive carrier that can produce any number of smaller vessels. During a mission, the Libra will automatically construct ships based on parameters set by the player. Captured planets and space stations can also produce ships, as well as increase the population cap. A mission can only be completed when all planets and installations have been captured and all enemy ships have been destroyed.
