Our city is under assault by a space invader! You are hired to protect the city and the world. Fortunately, the city hall is equipped with a line gun powerful enough to reach the space invader in the sky.
- Features -
1. Counter enemy's laser beam or falling bomb with the line gun installed at the city hall for a possible reward.
2. When a bomb lands right on or near a factory, a fire will erupt. Send a fire engine to the factory on fire before a huge explosion involves the entire city.
3. When the space invader becomes upset, it will toss an adult male or female it has abducted out to the sky. Save a falling citizen and get a guaranteed reward.
4. Call in an air reinforcement in time of trouble.
5. Protect the entire city with electromagnetic shield. Press S to turn on or off the shield. You must lower the shield in order to fire the line gun at the space invader.
