In Dirty Harry's Thunder Drive, you have two goals:
One, drive your car into the city's busiest highway and cause the biggest, most entertaining chain of destruction you can.
Two, use the rubble and spare parts you collect to rebuild and upgrade your own car.
Upgrades
The more destruction you cause, the more funds you earn to upgrade your stallion. Equip your car with dynamite for explosive power to send oncoming traffic flying. Or try a huge wrecking ball welded to the chassis to sweep out any cars, palm trees, or unlucky citizens it touches.With Speed and Armour upgrades available too, you can transform the beast into a reinforced speed-machine. Then, as you build up your skill you might find yourself flying and flipping through the air in a ballet of carnage.
