This is basically The Terrible Terrible Turret multiplied by 12. Though, this really began as a hack of Helipong.

Light up the night sky with a scintillating array of automatic laser fire! Use the arrows to rotate the ring of cannons, and see how long you can last before they are destroyed in a glorious blaze.

TIP: Get a friend to watch you play so they can tell you how cool the screen looks.

Oh, and here's something neat: unlike The Terrible Terrible Turret, I randomised the variables in the attack progression sequence. So, you'll get a slightly different kind of laser show every time you play.
