The empire strickes back

If you have a rapid fire controller (or very fast fingers) you can destroy the Walkers twice each and be awarded double points. Every 8 shots weakens it one color, and 48 shots destroys it. Blast a yellow Walker to hell and if you can hit it 8 more times after the 48th hit before it disintegrates you'll destroy it again. Saving the last shot for the bomb hatch will give over 250 points.

Frying produces various effects with the walkers such as fast walkers, backward walking ones, or walker-free planets.
