Installation 02

Installation 02 is one of the seven Halo Rings. Very little is known about it and it has yet to be directly observed.

In 2552, during the Battle of Installation 05, a signal was sent to this Halo from Installation 05, putting it on standby mode. A readout from Installation 05's Control Room showed that Installation 02 was fully prepared to fire on demand.

A more comprehensive readout was later observed in the Ark during the Battle of the Ark by the Arbiter, Master Chief, and Prophet of Truth, once again displaying that Installation 02 was on standby mode, waiting to recieve the signal to fire.
