Independence Day

Trivia

In each city or area, there is always a secret level that takes you to a place where you can gain extra life and new planes. They are hard to find and you usually run into them accidentally. If you look for them hard enough you'll find them. They are kind of like little time warps. The stuff in them with help you better off in the game.
