It is the year 2053, and a huge amusement park called Gateway Islands has been created on a small group of islands in Tokyo Bay .... The most popular amusement of all is the Rocket Coaster - a tight-speed ride which allows you to experience the excitement of speeding through a holographic virtual reality space while experiencing the bumps and shakes of a normal ride. Unlike the old jet coasters, which moved along fixed paths, you ride the Rocket Coaster on board a special vehicle with a jet engine called a "Krono Gear," which allows you to race freely through your virtual reality environment. Of course, if you make a mistake, you'll crash! Can you make it within the time limit?
