These graphics weren't used in the final game, Psygnosis' landmark 3D animated sequences were used instead. This was taken from a promotional Psygnosis slideshow.
The WIP image shows that there were several big changes done to this image while it was created.
The background was completely redone, the battleship was scaled down. The contrast between light and shadow areas was reduced to make the shapes more recognisable, although making the final image less dramatic.
