There is a secret stage after you win the Ice Cave stage. It waits for a player who can complete
all three bonus stages and all seven regular stages.

Goliath Defense

The third bonus stage is played after Fortress if you have already won the first two bonus
stages.

Shuttle Defense
By: Duros Bith

To reach the second bonus stage you will need to complete Tokyo, Pacific Ocean, and Air
Battle very quickly. If it's sunset when you reach the Desert stage you're already too late to save
the shuttle.

To reach the first bonus you must complete Tokyo and the Pacific Ocean stages with a very
high score.
