The Chief, The Blue and the Ugly
The Master Chief and Cortana have been adrift on the UNSC Forward Unto Dawn for over 4 years. The Chief has been in chryosleep for much, if not all, of that time. Upon John’s awakening by Cortana he discovers they are beside the planet Requiem and being drawn in – interestingly this is the planet seen in the Legendary ending for Halo 3. Cortana informs him that the ship has been boarded and while investigating the ship it crashes down on Requiem.
