Installation 04: Difference between revisions

Installation 04 orbited the massive gas giant [[Threshold]], and was suspended in the [[Lagrange point]] between Threshold and its largest [[natural satellite]], [[Basis]]. The installation had a 24-degree axial tilt from Threshold's orbital plane. Due to this, any given point on the surface of the ring received sunlight from the star [[Soell]] for half of the time it was on the sunny side of Threshold, and none when was on the dark side. This created a somewhat unusual day-night cycle for the ring, in which it was dark three-fourths of the time and had no sunrise or sunset similar to those of a planet.<ref>'''[[Halo: Combat Evolved: Sybex Official Strategies & Secrets]]''', ''page 64''</ref>

==History==

====The ''Mona Lisa''====

{{Main|Skirmish on Mona Lisa}}

Following the return of the survivors from the battle, the Office of Naval Intelligence learned of the Flood lifeform. Section III sought to establish a research laboratory in order to control the Flood parasite and possibly weaponize it against the Covenant. A science team headed by Major [[John Smith]] was authorized to take command of the [[prison ship|prison vessel]] ''[[Mona Lisa]]''. After bringing a group of Covenant prisoners aboard, they jumped to the wreckage of Alpha Halo in the Soell system. Some Flood specimens had survived the ringworld's destruction and were recovered to be experimented on both human and Covenant prisoners. However, the Flood soon broke quarantine and infected the ship. ONI later dispatched a [[prowler]], the {{UNSCShip|Red Horse}}, to assess the status of the ''Mona Lisa'' under the pretenses of investigating Halo's debris field. On October 25, 2552, the prowler was forced to destroy the overrun vessel with a [[Shiva-class nuclear missile]].<ref>'''Halo: Evolution - Essential Tales of the Halo Universe''', ''The Mona Lisa''</ref>

While the design of the Halos has stayed largely consistent across all post-''[[Halo: Combat Evolved]]'' media, Installation 04 underwent a significant visual overhaul in ''[[Halo: Combat Evolved Anniversary]]''. The entire superstructure of the ring has been redesigned. To wit, the surface features are completely different and much more pronounced, including additions such as rows of prominent prongs lining the ring's edges and large-scale patterns of bluish light. This redesign has not been carried over to post-''Anniversary'' media: the prongs are absent from [[Installation 03]] in ''[[Halo 4]]'', and [[:File:FUD-HaloRing.jpg|a visual allusion]] to the Halos in ''[[Halo 4: Forward Unto Dawn]]'' follows the original design. However, the "prong" design does make a subtle appearance on the outer shells of the arcade machines for ''[[Halo: Fireteam Raven]]''.
