A cinematic for Halo 5 Guardians has leaked online.
The video briefly shows Agent Locke talking to the Arbiter. It actually starts with Locke being told by another Sanghelli that he is not trusted, before the Arbiter walks in to start a conversation. The Arbiter begins to interrogate Locke on his job and his current mission. Clearly, this clip was stolen as it switches to a previous menu twice, and the audio gets broken up, before cutting off completely.
Most noteworthy in the clip are the recognizable voices of Keith David, playing the Arbiter, and Mike Colter as Jameson Locke. Similarly, there should be no doubt anymore that Agent Locke is front and center as the lead character for this new game.
You can watch the brief snippet below. Halo 5 Guardians will be released on Xbox One early 2015.
