Quick notes
- Master Chief is the returning Spartan. John-117 is the human player character in solo play and player one’s character in co-op.
- The Arbiter fights on your side. Thel ’Vadam is an Elite whose allegiance has changed since the Covenant civil war.
- Cortana is more than a mission voice. Cortana is the AI companion Chief is trying to recover.
- Johnson and Truth represent opposing objectives. Johnson is a recurring UNSC ally who helps Chief’s operations, while the Prophet of Truth leads the Covenant forces trying to activate the rings.
