Facility B3 is the lowest and most secure level of the Ibis Island research facility, consisting of the lower portion of the Third Energy Generator, a dedicated freight area and several exit and escape routes used for logistics and emergencies. A crucial part of the facility's transport installations, the Port, is located entirely on this floor. This level is connected to level B2 via the Central Stairway, and to all floors (minus 2F) with a personnel elevator in the Rest Station. The Large Elevator also descends to this level, connected to a second Carrying Out Room.
