My strategy is to go for warp. It's the coolest feature! I do this by focusing on the top lanes during the early waves. The top lanes advance the orange bonus multiplier. When it reaches 10X, warp is lit at the top left standup target. You have to drop the two pods first. When the ball is in the top lanes, you have to keep using lane change while guessing which lane the pop bumpers might push the ball into. I don't try for multiball, but when it happens, I use it to mash the drop targets and get to later waves. There is no objective in multiball and no scoring multiplier.
To open the right-hand gate, complete both waves of swarmers. This is easy to do with a smart bomb if both pods have already been opened (targets dropped).
There are 15 landers per wave. Keep track of them while playing. Don't just slam the smart bomb on a drain. If all the landers aren't out yet, then you have to start the wave over on the next ball, and you've wasted the smart bomb.
My best game so far is around 4.4 Million. I warped twice and got to wave 23. At that level, the drop targets and baiters are in constant motion. It sounds like 6 games, all doing ball search, all at once.
The problem with my game turned out to be the solenoid selector relay. I replaced it with a different style one that I stole off of an old Laser War playfield, works great now.
I love this game, but I do seem to hit the wall when the game thinks I have had enough. Lots of scores in the 2M - 3M range. Even more scores under 1M.
