The barren surface of SR388 was notable for its rough, rocky and dry terrain. Gamma radiation constantly pounded the planet, making it difficult for any species to inhabit the surface. Underneath SR388's surface was a vast maze of tunnels and rivers of lava and acid. Since the planet was once inhabited by the Chozo, it is safe to assume that they created much of the underground complex. The lava on SR388 blocked off many of the underground caverns and ruins of the planet. There were also frequent earthquakes that occurred and when they did, it usually happened in conjunction with the lava level decreasing, often-times exposing new caverns or ruins to be explored. sr388 has since been transformed into a habitalbe planet by prevously dormant chozo technology. Its surface is full of lush plant life. however due to the X parasite the planet is restricted access. that's the offical story, the unofical and classafied story is that the wreckage of the space station Biologic Space Laboratories research station is still being recovered and contains sensitive data that could incriminate certian parts of the Federation. The planet is protected by a entire fleet of Federation warships with orders to stop or shoot any craft entering the system without a escort. The Metroid DNA Vaccine is required to venture to the planet.
