Ascension, Coagulation, Sanctuary, Zanzibar. All are maps being revamped for the lovely Halo: The Master Chief Collection. Want to see clips of these in action? Then head below, fellow Spartans.
The video shows small clips of the maps along with commentary from executive producer Dan Ayoub explaining how the maps were revamped without changing the "flow".
It's all very interesting for Halo fans.
Halo: The Master Chief Collection will release on Xbox One November 11 and Halo 5 is expected in 2015.
