Wow, the screenshots look nice.
Actually, that description of Cyber Sled sounds a lot like the Saturn version of Assault Rigs (I'm not saying it's the same game - it's not). In AR you control tanks in a virtual world and blow each other up as well... and the worlds are like mazes with multiple rooms, ramps, obstacles, etc... I own the original CD of Assault Rigs and it also is a pretty rare game, as well as a PlayStation conversion.
