Charlie and the Misfits have been invited to join the closed beta of a new space-themed MMO, Star Nova Online. Together with hundreds of other test pilots, they hope to defend Earth from a descending menace. The Roth—a lizard-like warrior race—has nearly wiped humanity from the face of the universe. However, in a special event, the players successfully destroyed the alien outpost on Mars. With nowhere to retreat, the surviving Roth forces are left with one option. To destroy what's left of mankind in an all or nothing battle set to take place over Earth. Charlie and his crew have just seven days to train and prepare themselves.
