To the right are some very early pictures of Gunhed from March-April 1989. The pics show a stage set over the earth and ocean, never to be seen again. (Click on any of the screenshots for close-ups.)
NEC Avenue Golf
Below is an interesting golf game by NEC Avenue that, as far as I can tell, was never released at all. One interesting thing to check out are the graphics for the 1st-person view as well as the shot power meter. They look extremely close to another unreleased NEC AV game, Space Fantasy Zone, don't they?
