Robotech Wars - Third Robotech War

The Invid invasion in 2031, depicted in the third saga of Robotech known as The New Generation, destroyed what was left of the Army of the Southern Cross and the United Earth Forces (UEF) and left Earth completely devastated. The Invid established a central hive, Reflex Point, in the Great Lakes region of North America over the site of the remains of the SDF-1, and secondary hives across the planet. The Invid immediately began hunting down and destroying any and all remaining military personnel, and set up an aggressive operation to harvest the Flower of Life (and the protoculture it yielded) utilizing the remaining civilian human population as forced labor.

The Invid also began experiments to improve their survivability, including experimenting on captured humans. Some humans collaborated with the Invid in exchange for power and/or protection and helped hunt down those who resisted or helped with the harvesting and management of Protoculture. Many humans escaped the notice of the Invid by relocating to remote areas where the Flower of Life was scarce such as the mountains, deserts, and wilderness, with some even reverting to simple hunter/gather communities. Areas not under the control of the Invid were often ruled by criminal gangs and self-appointed leaders who ruled through brute force.

Fortunately, the Robotech Expeditionary Force (REF) had long been self-sufficient with the help of other recently established extraterrestrial settlements, and was only minimally hampered by the loss of Earth. In addition, Moon Base ALUCE (Advanced Lunar Chemical Engineering) was also able to continue to function despite its close proximity to Earth. Space Station Liberty was also able to continue to function. Unfortunately, events in deep space that kept the REF from sending aid during the Second Robotech War continued to plague them and kept them from turning their full attention to reclaiming Earth for another decade.
