Secret to Astro Barrier!

[Scootz]

I found this in the newspaper:

Astro Barrier Secret Levels

You haven't mastered this arcade game until you've completed the secret expert levels. To enter the Astro Barrier expert levels, wait 30 seconds between levels 30 and 31 and shoot the blue ship that appears.

I haven't tried it yet, but it sounds cool. :D

Yep, I've done it before. It works too. It takes a long time to get that far, though, so I've only done it once. It's pretty cool. :)
