This corridor is an S-shaped corridor, with the Hall vestibule and underground power distribution room doors located against one another on the northwest side, with the door to the sterilisation room on the south-east. The corridor is frozen due to the facility no longer being able to retain its warm temperature.
Two Green Herbs and a Blue Herb can be found in this corridor. The Blue Herb is on the north-east side approaching the underground power distribution room, while the two Green Herbs are found together on the south-west side leading to the sterilisation room.
It hasn't been used for quite a long time.
Door to the sterilization room
It's locked. This should open if power were to be supplied...
