Control Room (Installation 04)

"Unfortunately, my usefulness to this particular endeavor has come to an end. Protocol does not allow units with my classification to...perform a task as important as the reunification of the Index with the Core. That final step is reserved for you, Reclaimer."

Halo Installation 04 's Control Room was the site that controlled all of the ring's operations.

Description
The control room is located in a subterranean level below the surface of Halo Installation 04. The facility was built directly into a giant artificial cavern and protected by several sets of massive, presumed blast-proof, doors.

Inside there is a large circular bridge that is lacking supports. The bridge ends in a circular walkway. Both the bridge and walkway are made out of a reflective metal. In the center of the walkway there is a hologram of Threshold, Basis, and the ring between the two. .

On the outside of the walkway there is a model of the Halo ring itself. The model displayed a detailed map of the terrain and slowly rotated.

There is a single computer terminal in the room where the Index is places to activate the rings. The terminal also reported the weather, rate of spin, information on the machines keeping the ring running, and information on the outbreak of the Flood.

History
In 2552, after the UNSC ship Pillar of Autumn crashed landed on the ring, Covenant scouts came across the control room, presumably through use of the Silent Cartographer.

When the Master Chief John-117 came across the control room, he integrated Cortana into the interface. Absorbing the wealth of knowledge, she informed him of a terrible secret and sent the chief after Captain Keyes and his squad who were going after a Covenant weapons cache.

Later, Halo's Monitor, 343 Guilty Spark, brought the Chief back to the control room in order to activate the ring. When he learned what the ring's true function was, the Chief yanked Cortana out of the panel and raced to stop the activation process.

Gameplay
The location appears twice in Halo: Combat Evolved.
