Cyclone

"Cyclone" is the UNSC codename for a location on the Forerunner Shield World of Requiem.

History
During Requiem campaign in 2558, the Covenant remnant used this location as a supply depot, storing large amount of Covenant and UNSC weapons within the central structures' vicinity. Fireteam Crimson was sent in to destroy the plasma depositories, and in the process, the Spartans discovered discarded HAVOK missiles, but the warheads were removed. Fireteam Crimson was then extracted to assist Fireteam Switchback. The Covenant forces then 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. After destroying the artilleries and their conduits, the Spartans returned to extraction point and left the area. At some point, the UNSC had documented this area into 's simulation combat deck for Spartan-IV training.

Trivia
Cyclone is the location for the multiplayer map Vortex, making Vortex the third multiplayer map to be featured in Spartan Ops.
