I personally hate this game, and it is based on chance sneakdog because you do not know what kind of car will appear. It's just by chance. Eiter way it was annoying.
@Untio, try zone 3 you'll have soo much fun with Gunslinger, difficulty is practically exponential, so I don't know what your talking about. The first two zones are supposed to be Easy, the developer says so on their site.
