The Restricted Laboratory was located in the Restricted Zone of the Biologic Space Laboratories research station. It is found in a separate area at the bottom of the Main Deck and is connected to Sector 1 (SRX) and Sector 6 (NOC); the lab was designed to be detached in case of an emergency or a security breach. The Galactic Federation built it to house the captive-bred Metroids that they created from the DNA of the last Metroid.
