Well. i have been looking for this one game that i played was pretty sure on sega saturn, i been looking for it for 6 years and never found the name of the game...
You drive a vehicle forward in each level, you see it from the rear, and you drive straight, you can shoot a basic machine gun but you can also unlock better weapons to destroy towers and other vehicles i believe. in this game i think level one was a sandy, dirt like track, sky was black? where all you can do is go straight, you can however go left or right a tad bit to dodge upcoming objects, (but ultimately going forward). you can also go forever left or right as the levels loop over and over. if you went left to far, you come from the right side of the level, this border of the loop is mostly a ridge like mountain you can drive over on each side.
at the end of this first level, you encountered a boss vehicle, where you had to destroy it, or die.
i also remember another level, where you drive a purple truck of some sort, the sky and fog is bluish, and your main attack was a lighting bolt that destroyed anything in front of you that was close enough.
anyone help me?
