You drive some kind of war tank through a really dangerous road. You have the power to accelerate, break, jump, and fire a cannon. The game showed promise but then midway not the first level I ran into a seemingly impassable barrier. It was a big pile of rubble that killed me if I touched it. I tried to shoot it, jump over it, drive around it. Always death.
Regarding ‘Breakthru’: you have to accelerate real fast and then jump. Then you’ll be able to jump over that barrier. Also try to jump over the part that is at the lower part of the screen.
