Quoted from Waxx:
I've gotten a monster score on it before, I will have to look up what that score was but I think I made it through the Lieutenants and got the Super. I love this mode and I sometimes try for it just because. The rules really incorporate the story and personality of the theme.
I focused on this for a while a couple of months ago. Got it up to 2.8B+ Winter Has Come. I went with Greyjoy, Did Tyrell First (to get HotK shot multipliers), Stark (for boosted winter is coming), and Lannister for multipliers. Was able to play HotK and focus only on battering ram. Got it up to 5x, dumped balls down to 1. Then shot for Winter is Coming with playfield and shot multiplier, and was right at 400M for that one shot. Then proceeded to get the rest and keep it high. So my Winter is Coming was at 600M, which is important as that factors into the SJ value in Winter Has Come.
Probably the most fun and intense game I had on this game was that goal, and the stress during that multiball if you can't make shots!
