Editing Control Tower

{{Status|Canon}}

In order for the [[Astroengineering|installation]] to maintain the vast variety of life the Forerunners had collected from across the [[Milky Way]] for eventual [[Conservation Measure|reseeding]], a flexible environmental system on the Ark was essential. Working similarly to the output nodes of [[mass-particle replicator]]s or the archaic 3D printers of the 22nd century, the towers are capable of generating kilometers-deep environments around them through manipulation of raw materials stored deep within the superstructure of the Ark, meaning all habitable surface area could be covered in an environment to match any life-sustaining planet in the galaxy. Atmospheres, soil and vegetation makeups, bodies of [[water]] or other liquids, and even gravitational conditions generated from the base of each tower could be custom-set in areas as large or as small as needed to sustain collected specimens from a particular planet.{{Ref/Reuse|Control Tower log}}

When an environment was complete, only a small percentage of each Control Tower remained visible above ground in order to minimize interference with the new local wildlife while still allowing for data gathering on the surrounding area.{{Ref/Reuse|Control Tower log}}

In March<ref>'''[[Halo Wars 2]]''', ''[[Phoenix Logs]]'' – "Alice-130 Report #1"</ref> and May of [[2559]],<ref>'''[[Halo Wars 2]]''', ''[[Phoenix Logs]]'' – "The Blinded"</ref> several of these mostly dormant Control Towers were reactivated by the [[UNSC]] [[UNSC Armed Forces|forces]] of the {{UNSCShip|Spirit of Fire}} and a [[Covenant]] [[Covenant remnants|splinter group]] known as the [[Banished]] during their [[Second Ark Conflict|battle]] on the Ark. Professor [[Ellen Anders]], with the help of [[Red Team]] and other UNSC forces, used three of these towers to seize control of an elevator leading up to one of the Ark's [[Cartographer]]s.{{Ref/Reuse|A New Enemy}} Later, on [[Installation 09]], Red Team seized control of three more of these towers, allowing Anders to take control of a [[Retriever Sentinel]] and blast through the Banished's shield around the Halo's [[Control Room (Installation 09)|Control Room]].<ref>'''[[Halo Wars 2]]''', campaign level ''[[The Halo]]''</ref>

Control Towers were also used as part of a security measure for a Forerunner hangar, where a {{Class|Despair|fighter}} was stored. These also generated rear shields for [[Controller Sentinel]]s. During [[Operation: SPEARBREAKER]], [[Sunray 1-1]] took control of five of these Control Towers to disable the cloaking shield over the hanger.<ref>'''[[Halo Wars 2: Operation: SPEARBREAKER]]''', campaign level ''[[Gatecrashers]]''</ref>
