==Cairo Station Commons Blue==
Cairo Station Commons Blue was the United Nations Space Command portside commons of Cairo Station closer to the bridge. During the Battle of Earth, Covenant boarders invaded Commons Blue, pushing back Marines to the far side of the room and pinning them down by overlapping fields of fire from Plasma Cannons on the "islands," along with Unggoys and Sangheilis. However, they were repulsed by John-117.
