The new spartan posed opposite Master Chief as though a reflection in Halo 5: Guardian’s key art is one Agent Locke, 343 Industries studio head Bonnie Ross told Eurogamer during E3.
This new Spartan—whose armor seems a tad more advanced than Chief’s Spartan-II Mjolnir armor (perhaps Spartan-V, or some hybrid of Spartan tech and alien tech)—will have his origins explored in the Ridley Scott–produced digital series Halo Nightfall. This, according to Ross, is meant to give characters foundational knowledge of Locke, who will serve a “key role” in Halo 5.
Halo Nightfall will be among Halo: The Master Chief Collection’s extras. The Master Chief Collection, which launches November 11 on Xbox One, combines all four core Halo titles—1 through 4—in remastered form running in 1080p resolution at 60 frames per second.
