Gunner

A drifting ex-soldier turns underground fighter with the help of a just-released ex-con, pitting him against corrupt cops and hired killers now gunning for him and all those he cares about.

Set between the events of Halo 4 and Halo 5: Guardians… Halo: Nightfall tells the dramatic story of legendary man hunter and Naval Intelligence Officer Jameson Locke and his team as they are caught in a horrific biological attack while investigating terrorist activity on the distant colony world of Sedra. As they unravel a plot that draws them to an ancient, hellish artifact, they will be forced to fight for their survival, question everything and ultimately choose between their loyalty and their lives.

Major Daniel Kirby takes command of a squadron of Marine fliers just before they are about to go into combat. While the men are well meaning, he finds them undisciplined and prone to always finding excuses to do what is easy rather than what is necessary. The root of the problem is the second in command, Capt. Carl 'Griff' Griffin. Griff is the best flier in the group but Kirby finds him a poor commander who is not prepared to make the difficult decision that all commanders have to make - to put men in harm's way knowing that they may be killed.

Two brothers compete in the world's deadliest underground fighting tournament, where they must decide whether to play by the rules or to cast their honor aside and team up to bring down the dark syndicate running the tournament.
