Moon Base: the first permanent human colony on the Moon, this was primarily a scientific research station, but was also a secret military research facility (a fact unknown to many of the base's inhabitants). In 2035 Anti-Unification forces killed the crew of the Base with a hijacked Oberth-class space frigate. The base remained abandoned for several years until, an unknown signal started transmitting back to earth.
The governments of the varying nations of Earth jumped into action, each launching space shuttles to uncover the clues of this long lost facility, and more importantly, to be the first ones on the base and lay claim to what had been forgotten there years ago.
