Liberty

War.
It rages across United Earth space, claiming millions of lives. The Swarm have returned, larger, more fierce, and more technologically advanced than ever before.
The voice from Saturn's moon Titan claiming to be Tim Granger is warning humanity that this time, the Swarm may be unstoppable.
Admiral Shelby Proctor, on the run for the suspected murder of the United Earth President, knows that humanity's only hope may be a hero that's been dead for thirty years, and travels to the center of Titan to find him in Earth's darkest hour.
The fleets are assembled, all the races united against the overwhelming enemy from another universe. And now all they need a legendary hero to lead them to victory.
