This particular cut scene was supposedly meant to bridge the gap between The Master Chief Collection and Halo 5: Guardians, and it is said to have been shown by accident in the midst of a Twitch stream of The Master Chief Collection.
In that alleged leaked scene, it points to Agent Locke talk to Arbiter, as they continue to discuss “the hunt” when it comes to Master Chief. This would more or less point out that Locke is about to be an integral part of the story of Halo 5: Guardians. Many of the mirrors, and if I am not mistaken, all of them eventually, will be removed – so the case of “the early bird catches the worm” applies here.
Are you looking forward to the release of Halo 5: Guardians? If so, would you be willing to purchase a spanking new TV in order to enjoy the title as it rolls out?
