Unknown Biological Infestation

Late into the events of System Shock an Unknown Biological Infestation began to overtake parts of Citadel Station. It was first encountered in a small part of Executive (Level 6), near Edward Diego's quarters. Another prominent infestation was seen near the Elevator from the Security Level (Level 8) to Level 9. The Bridge (Level 9) was almost totally infested. Not much is known of it except that it was most likely created on Citadel Station.
