The cut scenes were created by the well known Hollywood CGI company Blur Studio and will be included in Halo 2: Anniversary, which itself will be bundled as part of Halo: The Master Chief Collection, which brings Halo 1-4 to the Xbox One.
Halo 2: Anniversary will also feature revamped graphics for the game itself as well as new versions of several of its multiplayer maps. Today, as part of its San Diego Comic-Con announcements, developer 343 Industries revealed that the Zanzibar map from Halo 2 will be remastered for the Anniversary version. Halo: The Master Chief Collection will be released on November 11 and will also include the full version of the live action digital feature Halo: Nightfall, as well as a code to access the upcoming multiplayer beta for Halo 5: Guardians.
