Cross Section: Screen shots

This is what Nebulus looked like on a Commodore 64.

The actual image is not taken from such a machine, however. It's running in a Commodore 64 emulator on a Power Macintosh.

This is another emulated screen, of the Atari ST Nebulus version, which was released a year later.

Although the Nebulus towers look rather flat in still images, due to the lack of a proper illumination model, the 3D effect was highly convincing when the game was in motion. (And the water reflection in the ST version was enough to make even hardened computer game players drool.)
