The main goal of the game is to save Las Vegas by destroying the asteroids. You must not allow any asteroid to reach the ground: place bombs around in the sky in order to destroy them.
Your final score is determined by:
- The number of destroyed asteroids.
- Precision at destroying asteroids.
- Survival time measured in days.
The first time you play, some hints will be shown for you to understand how to use the weapons and how to pick up parachutes. The game will become harder and you will be able to pick up new weapons. The screen becomes wider and you have to scroll the scene in order to defend the whole city.
