There is one other way to boost your Nitrox levels. Use them well and you can zip past or even over the other cars. This boost power is necessary on courses that have straight stretches and ramps. Fill it up, hit the boost button, and off you go like a bunny rabbit on speed. To power-up, golden rings can be collected in order to boost the car's Nitrox power. Zip arrows are placed on a narrow track to speed you along. Gameplay Hot Wheels: World Race is a fast game set in the future. You think I'm kidding, but no, it exists and it's sure to please little kids who love their toy cars and nobody else.
The new Hot Wheels: World Race is exactly that. Now imagine that experience was a video game and that was all there was to it. Take a deep breath and try to relive those glory days for just a few seconds. I bet that when you were playing with your Hot Wheels back in the day, you used to do most of the same stuff I did: speed 'em around, flip 'em in the air, and make whooshing noises with your mouth.
