Control Room (Installation 05)

"What is that place?"

- The Arbiter

"Where the Councilors were meant to watch the consecration of the Icon: the start of the Great Journey."

- Rtas 'Vadumee

Installation 05 's Control Room was the site that controlled all of the ring's operations. Installation 05's control room is located on an island off the coast of a larger island in the middle of a large sea.

History
Prompted by the Prophet of Truth, Tartarus brought 343 Guilty Spark and Commander Miranda Keyes to the control room in order to activate the ring, initiating the Great Journey. However, before he could force Keyes to activate the panel, the Arbiter arrived, teaming up with Avery Johnson and other Sangheili troops. After trying to convince Tartarus to change his mind, Tartarus instead forced the Index into the panel, activating the primary firing systems. A battle began between the Sangheili and the Jiralhanae, which ended after Tartarus and his troop's died, but Keyes was able to deactivate the ring. It also has a difference between 04's Control Room: this one has three parts, or levels.

Gameplay
This is the location of the final level and a boss battle in Halo 2. In the game, the player must jump from the ledge where Johnson snipes, down to the gears of the control room that are charging up the Halo Ring. In the center of it, there is a large gravity lift that takes you to the top, regardless of where you are. There are three "stories" of to this part and on them are numerous gun crates to assist in battling Tartarus. Elites will attempt to aid you in defeating Tartarus, but they will fall in vain to the Fist of Rukt. On higher difficulties, Brutes will jump down to aid their Chieftain. To get down to lower levels, one must jump down to them.
