Overview & Background
Cortana is the highly advanced A.I. at the heart of the Pillar of Autumn. Her design allows her to be uploaded into an appropriately configured battle suit for increased mobility. She is capable of hacking into alien computer systems, and has used this skill to intercept Covenant communications during combat. She interprets this data to provide her caretakers with directional waypoints and the best available information about troop movement and strategy.
- Her design closely resembles how she appeared in Halo 4.
