The game Car Challenger offers more than just ordinary sightseeing tour. Each track has set its own time limit. After its successful completion, you will be awarded with points which can be used for upgrades and adjustments of your vehicle. You can invest into better engine, brakes, tyres, steering or into ability to drift more effectively. This feature unlocks a completely new dimension of gaming. Cars in default settings are rather lazy and difficult to handle. Once you get to the decent upgrades, they become unstoppable street predators which cannot be held back even by the ride on two side wheels. You say you have not seen anything like this before? You are right, it is world first premiere! Have fun.
