Cadet Michael "Sully" Sullivan continues to decode the hidden ONI combat video as Lasky's struggle with his place in the UNSC ignites with fellow cadet Walter Vickers. After a classroom confrontation with Captain Mehaffey and a challenge from Chyler, Lasky pulls Hastati Squad back from the brink...at a terrible physical cost to himself.
Sully's illicit intelligence video shows Hastati Squad that their world is even more complicated than they knew. Lasky’s collapse at the end of his brilliant field maneuver turns into a pivotal choice for him, and just as he and Chyler realize what that choice might mean for their relationship, the academy is shaken by the first blow of a terrifying invasion.
A 90-minute extended version is included with the Limited Edition version of Halo 4, and became available on Blu-ray, DVD, Xbox Video, iTunes and video on demand services on December 4, 2012.
