The game is divided into 3 parts. Code green - the training missions, Code amber - the policing missions and Code red - city evacuation. In each section you have a list of missions. Complete all the missions in a section to progress to the next. Police Chopper is controlled with the mouse. When you start a mission you will be given a brief. This will explain what you have to do to complete the mission. The first will teach you how to fly, the second how to land. Follow the hint arrow above the chopper to find the mission objectives. Collect 30 stars to gain an extra life. You can have a maximum of four lives. Each star collected will also reduce your mission time.
