Ok, here's some vague details.. The main jist of the game is, you're driving a hover car.. There seemed to be basic ramps on the sides of all the roads, you could drive (hover) on the side and make long jumps and stuff.. I want to say the game was ms-dos..

I think you basically shot stuff from the vehicle though I can't recall.. For some reason when I try to think of the title I think "dead zone" but I've checked and can't seem to find that relating to what i'm searching..

1 thing I'm about 99.9% certain about, the word "zone" is in the title. Thanks!
