This game, once again puts its focus on Sumner Sturgeon, who left the military at the end of New Wave, was marked as killed in action by the military. It takes place a few years after New Wave. Sumner has become a pro-lifter of sorts, lifting under different aliases to prevent anyone from realizing who he is. Sumner later partners up with Ruri, and Moondoggie, who left the Gekko due to abuse from the crew, to investigate a military development called CFS, otherwise known as the Compac Feedback System, which allows anybody to pilot an LFO like a pro, albiet with many drawbacks.
