The BIGS 2

The way I was able to score 1Mill+ pretty easily for each HR pinball venue was to use this technique. Times Square was the hardest, but still not bad.

1.Learn which target groups trigger the bonus target for the venue (they usually require between 3-6 hits to activate) and then hit all but one of the targets. Do this to multiple target sets (I prefer to get 3 or 4 groups to the point where they all have just 1 hit left to trigger the bonus), but don't trigger the bonus yet.
2.Acquire enough points to get your Big Blast meter full, but don't trigger it.
3.Pick off the last target of the groups you set up in step one. Ideally, you are looking to get a bonus target of x3 x4 or even x5, but x2 isn't bad either and I've even settled for multi-balll or pitch mania.
4.Once you trigger the bonus energize your Big Blast and proceed to hit the major targets at the venue that score the big points (i.e., fartest away targets, plus blimp at vegas and monster at tokyo). Since most of these targets score 50K, the points can really rack up quick especially if you were lucky enough to get the x3,x4,or x5 multiplier as your bonus target.
5. Rinse and repeat. I can usually score 1M using this technique by the time shortly after the pitcher has added his 4th pitch to his arsenal.

As a side note, if I have run though all the target groups I've preseeded in step 1 and don't unfortunately get a bonus multiplier. I'll usually go ahead and use my Big Blast without a multiplier in place and afterwards begin preseeding the target groups again, because that whole process will fill the Big Blast meter again, so it's pointless to save it at that point.
