Galvanize or Die

The chemical brothers most recent album has been one of the funkiest and best albums of the last 12 months or so and now they have got a fine(?) game for your galvanizing pleasure. I'm not really sure how it all works as I didn't bother reading the instructions but maybe someone can point out how I can kill all the aliens and galvanize myself against the evil. Plus you get to push the button, so what more could you want.
