History of Keymaster

Overview

Keymasters are Cabal enemies that carry keycards, which open locked doors during a mission. They appear throughout the Lightfall campaign mission First Contact, where a Keymaster's keycard is needed to progress past each locked door.

In First Contact, Keymasters include a Centurion Keymaster guarding the Restricted Area, an Incendior Keymaster in the first Escape Pod Hangar, a Keymaster in the Tormentor Room, and an Unstoppable Keymaster in the Final Hangar, whose key is needed to leave the ship. A Cabal Colossus carries the key for the Computer Core fight instead.
