Well that's simple. I think I said where the new loadout was at Vjun, you get the Concussion Rifle, and at Bast Castle, Lower Floor is where you get the Merr-Sonn, so its not that hard to figure out those.The saber changes are at the start of every tier, and the decision to get duals, staff, or single is at the start of the 3rd teir.
Also, I really don't think there is need to make two seperate walkthroughs for Light and Dark, since the only changes are that you either fight Dark Jedi only, or both Dark and Light, and then all you have to do is fight Tavion and Kyle.
Also also, I was planing on doing a run through the demo anyways, since you told me to a while back
Maybe just put that up instead.
