Following the personal story of Jameson Locke, Halo: Nightfall will delve into the world of ONI, the Office of Naval Intelligence within the Halo universe. As the Earth’s most powerful and secretive military branch, Jameson Locke will investigate terrorist “chatter” on the distant colony world of Sedra.

During his mission on Sedra, Locke, a legendary manhunter and ONI agent, will succumb to a biological attack and be forced into cooperation with Randall Aiken, a local commander with a remarkable history and deep-rooted mistrust of ONI. During the course of Nightfall, the ONI squad and Aiken’s team will fight for survival through the trials of mystery and find themselves among an ancient, hellish artifact.
