Halo 4: Forward Unto Dawn

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.

While Corbulo Academy is being destroyed by the Covenant invasion, the surviving cadets fight bravely alongside their only hope: The Master Chief.

After a terrifying night of combat and loss, Lasky makes a life-or-death decision to help the Master Chief... but will it be enough to save them all from the Covenant?
