Maintenance

Maintenance areas are numerous in UNSC vessels and can be used for easy passage through the ship. Some maintenance corridors have inter-floor ladders. In case of on-ship attacks, the corridors can be used to flank enemies.

John-117 used several Maintenance corridors on board the Halcyon-class Cruiser to attempt to stop the Covenant from gaining control of the vessel, as well as to make his way to the Lifeboats.

Maintenance access ways are marked with a green triangle on Halcyon-class vessels doors. The Maintenance crew are likely in green or orange fatigue uniform as well.
