Turbo Out Run
There are 16 stages set across the US, gradually moving from east to west, all depicted differently visually. After every 4 levels, you go into a shop screen, with a choice of upgrades. As the title implies, you now have a turbo booster installed, which speeds up the car, although over-use can cause the engine to overheat, and it is not recharged until each shop section. You have 5 continues, and failure to complete the course within the time limit costs you one.
