Quoted from Oneangrymo:
The more I play this Pin, the more Im like wow this is awesome... except for those damn drains which I still haven't adjusted. How do you get to the fight the emperor thing? And can someone please tell me more about this multiplier. When should I use it and when shouldn't I? Im still confused about that button in the middle other then for shooting all those tie fighters.
To fight the Emperor, you must complete all of the modes and the planet mb's, and, in addition, you must complete lightsaber duel, escape from Boba Fett, obtain 100 Tie fighters, as well as achieve Jedi Master. Once this has been accomplished, there will be green arrows pointing towards the left ramp to initiate the emperor battle. Once that battle has been completed, the character that you are/were playing will stay lit, and you will progress to the next of the available characters to play, i.e. Luke, R2D2, Han, Leia.
For me, I am still working on using the multiplier well during gameplay. The multiplier will increase every time you hit the 3-Bank targets by the Tie fighters underneath the small LCD screen. Either while the ball is in play about the pf, or while the ball is cradled on the flipper, hitting the lockdown bar button will turn the multiplier inserts from green to red, after which time you can use the left or right flipper to move them around. Once you have them where you want them, you tap the lockdown bar button again and it goes from red to green (green = activated multiplier). So, for example, you're in a mode that requires a right loop shot, if you have the opportunity, move the multiplier insert over to the right loop, make sure it's activated by turning it green, and then take that shot = obtaining that score plus whatever the multiplier is at....whew....hahaha. Remember, the elevated multiplier only lasts for a brief period of time and you can tell it is about to run out because you hear a fast beeping sound alarming you that your time with that multiplier is almost up. This can be continued or even increased by hitting the 3-Bank targets again.
Of note, the higher the multiplier gets, the fewer the inserts there are to move around...for example, when the multiplier is at 2x, 3x, 5x, etc. there may be three inserts, however, when it is higher such as 10x, 15x, or more, there may be only two or even one insert to move about the pf.
Other uses for the button would include starting a new game, selecting the modes you want, and...i think that's about it.
