Halo: Retribution

In December 2553, tensions escalate in human-held space following the assassination of UNSC fleet admiral Graselyn Tuwa and the abduction of her family, prompting the Office of Naval Intelligence to initiate a dangerous mission. Homicide detective-turned-ONI operative Veta Lopis must uncover the truth behind the violence as she leads a team of Spartan-IIIs against the suspected Brute dokab, whose connection to a Covenant splinter group complicates matters. As they dig deeper, Lopis and her team, aided by members of Blue Team, confront a malevolent plot emerging from the secret research station Argent Moon, threatening the fragile peace after years of conflict.
