In 1973, following the ruthless six-year-long Lunar War, the hostile alien species known as the BETA—Beings of Extra Terrestrial origin which are Adversary of the human race—invaded Earth, killing billions and decimating Eurasia. While BETA can be destroyed with conventional weapons, their laser-class is able to wipe out entire aircraft fleets, forcing mankind to develop giant combat suits called Tactical Surface Fighters (TSF) to combat them.

A short story, set some time in Total Eclipse during the events of Blue Flag, about the appearance of a "ghost F-4" in the TSF simulators, a spectral manifestation said to be undetectable and unbeatable. In 2001, reports are coming in from pilots regarding an undefeatable F-4 Phantom present in the simulator database that will forcibly insert itself into any active simulation, and defeat all human pilots present. Despite the simulators being locked down, Yuuya Bridges, initially being there just to check things out after having his interest piqued by Vincent Lowell, now has to team up with another pilot on the site, Lieutenant May, to get to the bottom of this phantom menace.
