Quoted from Taxman:The only thing I thought was strange was the upper right flipper had no dedicated shot.
I'm absolutely convinced that in order to kill the dragon, you're going to have one shot like with the TOTO shot in WOZ. You'll fire the windlance with the fire button, it'll shoot the ball up to the upper right flipper, and you'll have one shot at the hole behind the targets and beneath Smaug. BLAMMO!!!
Unfortunately, we have to wait for the DVD to come out for WB to release the footage from the third film of Smaug getting aced. Wonder what they'll put there instead in the meantime...
