Battlestar Galactica:Squadrons

If the world as you knew it was destroyed, how far would you go to get it back? The Cylons have returned to the Twelve Colonies after a forty-year absence. Bent on revenge, they unleash nuclear weapons powerful enough to destroy human civilization... and nearly succeed. The only survivors of the Cylon assault are a ragtag fleet of civilian ships and the last remaining Colonial Battlestar: Galactica. As Commander of Galactica, you must lead the civilian fleet through uncharted space in search of a new home, while defending it from relentless Cylon attacks. These machines never sleep; letting your guard down for even a moment will cause not only your downfall, but also that of the entire human race.
