Been seeing quite a few posts suggesting Chief is rogue. Where are people getting this? Honest question.
Possibly because the UNSC wanted Halsey assassinated, and she was the closest thing to a mother Chief had
Probably because on the poster, the person on top is from ONI (you can see the ONI emblem on the chest), and Master Chief is flipped upside (take a book out of Fable, and the mirrored person is the evil person).
