This will get you about 255 lives, 255 continues and 255 health points.

To play as an alien Kronn Hunter, you must shoot *only* the first three
STAAR Team members you see on the Front Tarmac (Wave 1), as
you start the game. Don't shoot anything else!
You will be restored to your starting number of lives, and you can play the
entire game (including secret rooms), and even get *two* unique storylines
at the end of the game (one mission failure, the other victory).
The powerups and stat plates are all different, too.

Kronn mode, if you can handle it, is the highest possible scoring mode in
Area 51. At each update stage, you will receive an additional 20,000
point bonus. It will also put up a green alien symbol on the high score
screen if you make it.
