I cannot for the life of me figure out how to dual wield weapons especially beam sabers. can anyone who has this game help? Do I have to be at a certain level or something?

can you even duel wield in this?

yeah, i feel like an idiot though... all need is more than one of the same weapon and it ask you to equip both... provided you have enough gen points
