You have to collect all the saucer lights by completing perfect modes to start "attack mars"

The secondary buttons are used in the final battle and in some of the modes.

You use the secondary buttons to aim on several modes such as Martian Bowling during the mystery round.

Haven't gotten to the final battle, so I'm not sure how they are used there.

Saucer lights can also be collected by performing well during the multiballs that happen after every three modes, and as a scoop award, so you don't have to be perfect, just close enough that you can plug your gaps with the bonus saucer lights.

The secondary buttons are used to change channels in TV mode, and the way they are used in the wizard mode will be pretty obvious -- there are crosshairs that need to be lined up with targets.

I agree the first time I played SWEP1 I was like ahhhh secondary buttons - thank god they finally got used.

It can be tough running a flawless game on RFM, especially on a Medium/Hard setting. I too ran the game today and I fulfilled all 9 modes and 3 Multiball Modes and I still had to complete a 10th mode before I had the opportunity to get a shot at Attacking Mars. I personally feel that the AM wizard mode is just too short.

I lit all saucer lights yesterday, and was on the last bonus wave multiball when I drained my last ball...

I assume I would have had to complete that multiball to start the Attack Mars mode?
