The space station known as the Third Moon is an artificial base that orbits around Earth and is large enough to be actually seen from its surface. Appearing on orbit around the same time Grandmaster Meio made his sudden appearance on Earth, it serves as his true residence. The truth behind the station remains a mystery, although rumors state it is a spaceship that has been usurped by Meio (according to the English intel, Meio built it himself).
The Third Moon plays a central part in Grandmaster Meio's plan to erradicate all the "messy" lifeforms on Earth so he can start a new, perfect race of his own making: by using a giant Gravitron unit installed within, Meio seeks to pull the satellite from orbit and enter the planet's atmosphere, an act that will cause several cataclysmic events such as earthquakes and tsunamis.
After being injured in his battle against Hiryu, Meio opens up a portal and transports himself to the Third Moon, closely followed by his nemesis. By the time Hiryu arrives, however, the station appears to have been completely destroyed, leaving only pieces of scrap and a set of Gravitrons in its place. Using the scrap as platforms to stand on Hiryu faces and defeats Meio in his true form, Meio Prime.
When Hiryu arrives at the area, it consists of a simple array formed by several pieces of scrap metal floating in front of the Earth, surrounding a set of 9 Gravitrons: five small models and four large ones, all arranged into a circular pattern around the area.
The center of the area has three Plasma Rings in a triangle formation (one high above, two below it), which helps Hiryu reach Meio Prime's weakpoint during the battle. The Gravitrons and scraps serve as platforms for him to stand on, and the former can also be used as shields to avoid Meio Prime's attacks.
While there are no actual item unlocks to search in this area, beating Meio Prime unlocks the final three Intels in the database: Concept Art #44 (Meio Prime), Character Intel #39 (Meio Prime - The True Form) and Story Intel #11 (Third Moon Base). Note, however, that these three will remain locked if the player doesn't save following the game's ending.
The Third Moon appears to have been originally intended to be a full-fledged stage, or atleast a more involved area than the simple boss room it ended up in the final game. Its English Intel bio describes a huge space station with a "giant" Gravitron unit, whereas the game itself shows simply a bunch of scrap metal surrounding a set of Gravitrons, of which none is bigger than the boss version. It's possible the station was destroyed by Meio Prime, although this is not shown in-game, as the transition between boss battles is quite abrupt.
Game artist James Paick released three pieces of concept art he created for Strider which feature a large space station. As all pieces share the same design elements, it is possible this was the intended look for the station.
