Cyclone

History
During Requiem Campaign in 2558, Jul 'Mdama's Covenant used this location as a supply depot, storing large amount of Covenant and UNSC weapons within the central structure's vicinity. After learning about it from a central intel center in the "Warrens," Fireteam Crimson was sent in to destroy the plasma depositories, and in the process, the Spartans discovered discarded HAVOK missiles. However, the warheads were removed. Fireteam Crimson was then extracted to assist Fireteam Switchback. It was later discovered that the removed nuclear warheads were taken to be used in an attack on the.

The Covenant forces later retook the area and placed three plasma artilleries in this area, allowing them to provide support to nearby troops. Fireteam Crimson and Fireteam Kodiak were sent in to neutralize these artilleries which were shelling Fireteam Majestic's position and pinning them down. The Spartans were able to destroy the heavily-shielded artillery pieces by targeting their power conduits and fought off a Covenant counterattack. The Covenant were aided by a Covenant listening post at "Lockup" using a downed Pelican to listen in on Spartan communications, but the defense and counterattack failed and both fireteams were extracted from the area.

At some point, the UNSC had documented this area into 's simulation combat deck for Spartan-IV training.
