Tips/Hints

And long walks on the wide open fields

Try and avoid levels that aren't in the wide open areas, otherwise you'll probably get stuck and blown by the wayside.

I like 'em big

Use the big heavily armed tanks and just grab power ups to blow away as many enemies as possible. Smaller tanks don't offer any better steering, and you might as well use tanks with more armor.

Fire Soon as you see the pixels on the screen

Don't bother saving your special weapons since your tanks won't last long. MIght as well use what you can.
