I still have yet to figure out what choices I am missing that'd get me all of the scenes unlocked. I've got around 80%-90% of them all unlocked right now. That said, I haven't made any choices that I'd assume would get MC any strike points, nor be a choice that'd in my mind fuck up the other characters (say be a dumbass and trust in Hollis forgiving the ahole in example). So I assume that'd be where I gain the remaining scenes I am missing.
