Microsoft has released a set of images of
Halo: The Master Chief Collection showing various scenes and Halo 2 maps in the original version and the
Anniversary . As you can see below the differences are remarkable: above all the cut-scenes are recreated in computer graphics, show deep differences. The scenes in-game you show much improved although not to the levels of what we want from a Halo next-gen, but probably with this source material you couldn't do much more.
