It was 2020. Six years had passed since the destruction of the Super Dimensional Fortresses 1 and 2, that final tragedy of the First Robotech War. But Earth was on the mend now, and from the wreckage of those ships the Robotech Defense Force had succeeded in fashioning a new battle fortress — the SDF-3. Its mission: to cross the galaxy and make peace with Tirol's Robotech Masters.
It sounded straightforward enough; but unknown to Admirals Rick and Lisa Hunter and their crew of thousands, the Robotech Masters were already on their way to Earth!
Nevertheless Tirol would have a greeting in store for the Expeditionary Mission: an incendiary salute from the warlord whose hordes had conquered half the galactic Quadrant — the Invid Regent! Threatened with a swift and violent end, and suddenly torn by internal struggles for power, the RDF would find itself thrust into a savage war for survival!
