Battle In The Sky

The Earth has been invaded by an evil alien race. And since you are the top pilot of the most advanced fighter craft around, you are the world's only hope ! You must battle your way through four different areas, until you finaly battle high above AREA 51, and face off against the leader of the evil aliens in his powerful spaceship. Each area you battle through has 4 different levels, at the end of each area is a BONUS stage, where you must fly your fighter craft through an Asteroid Field. Great rewards can be found in the BONUS areas. Some of the asteroids when shot will explode and release a Power-Up capsule which floats around the screen. Touching the Power-Up capsule gives your fighter craft awesome powers.
