SOUTHERN CROSS
The Robotech Masters have come to Earth to finish the conquest their Zentraedi warrior-slaves had begun… A battle-ravaged planet must defend itself once more. Dana Sterling, half-Human, half-Zentraedi commander of an elite Hovertank unit, must step into the spotlight of interstellar history!

Who better to brave the ship than Dana Sterling's 15th Squadron ATACs—after all, they brought the thing down to begin with!

THE FINAL NIGHTMARE
The Robotech Masters' Protoculture Matrix is degenerating, transforming into the Flower of Life—sure to draw the savage, merciless Invid across the galaxy to Earth.
