Jameson Locke is an all-new character in the Halo universe, and Halo: Nightfall webseries, which takes place between Halo 4 and Halo 5: Guardians, tells his origin story. Locke is an operative of the Office of Naval Intelligence, which is the toughest military branch the Earth has. He and his team must uncover the truth behind an artifact that can kill humans – and who is trying to use it against them.
Halo: Nightfall will launch this November.
