This game uses a blend of movie files and hardware effects for the backgrounds
and generates the actual enemy ships and main ship polygons in hardware. Some
claim that the cut scenes, and flat shaded polygon areas of the levels are movie
files. I've never been convinced this is true however.
If these pics are from movie files, they are the absolute most clear digital
movies ever made. There are no artifacts or grainyness, and the polygonal ships
even sport a large amount of aliasing issues as well.
