Door: Difference between revisions

The [[Covenant Empire|Covenant]] frequently use curves as well as bright purples, blues, and grays in the design of their technology; everything from weapons to cities. The doors incorporate the curves and colors standard to Covenant design, most notably in [[High Charity (Structure)|High Charity]]. While many doors throughout the Halo Universe have indicator lights and work by sliding in and out of the walls, only the doors in High Charity flash when the player gets close and emit a tone.<ref>'''[[Halo: Combat Evolved]]''' ''level [[The Truth and Reconciliation (Level)|The Truth and Reconciliation]]''</ref><ref>'''[[Halo 2]]''' ''level [[Gravemind (Level)|Gravemind]]''</ref><ref name="Cortana">'''Halo 3''' ''level [[Cortana (Level)|Cortana]]''</ref>

[[Human]] technology for doors has progressed since the modern era. While most doors today are based on a hinge system, the doors seen on Earth are almost exclusively sliding (except for the antiquated doors in [[Crow's Nest (Base)|Crow's Nest]]),<ref>'''[[Halo 3]]''' ''level [[Crow's Nest (Level)|Crow's Nest]]''</ref> either opened by proximity or a switch located on the door itself. Like most human technology applied to everything from roads to spacefaring military vessels, the design is simple and geometric (with some discrepancies) with straight lines and angles, and involves blacks, grays, and browns. Most doors have a light on them that is either green to indicate that it is open or can be opened, or red to indicate that it is locked.<ref>'''Halo: Combat Evolved''' ''level [[The Pillar of Autumn (Level)|The Pillar of Autumn]]''</ref><ref>'''Halo 2''' ''level [[Cairo Station (Level)|Cairo Station]]''</ref><ref>'''Halo 3''' ''level [[The Storm (Level)|The Storm]]''</ref>

Doors built by the [[Forerunner]]s are completely geometric and incorporate the similar light grays, browns, and blues of the rest of their technology. The doors themselves are geometric and often slide in multiple parts. They also have complex and geometric designs on them, it is often patterned. This same trend can be seen on floors of Forerunner structures.<ref>'''Halo: Combat Evolved''' ''level [[The Silent Cartographer (Level)|The Silent Cartographer]]''</ref><ref>'''Halo: Combat Evolved''' ''level [[Assault on the Control Room (Level)|Assault on the Control Room]]''</ref><ref>'''Halo 2''' ''level [[The Arbiter (Level)|The Arbiter]]''</ref><ref>'''Halo 2''' ''level [[Delta Halo (Level)|Delta Halo]]''</ref><ref>'''Halo 2''' ''level [[Uprising (Level)|Uprising]]''</ref><ref>'''Halo 3''' ''level [[The Ark (Level)|The Ark]]''</ref><ref>'''Halo 3''' ''level [[The Covenant (Level)|The Covenant]]''</ref>

While the Flood do not have what we consider conventional architecture, they build their structures out of biomass they have consumed. Their doors, called [[Porta]]s, are built from biomass of infected hosts, and resemble valves like those in the heart. They open based on proximity. While the sections of the door itself retract, the circular frame of the door contracts at the same time. This effect was most likely added by Bungie to make the player feel as if they were playing inside a living thing during the level, and add effect to the level.<ref name="Cortana"/><ref>'''Halo 3''' ''level [[Isolation (Level)|Isolation]]''</ref>
