So I noticed that several of the Exotic weapons can only be acquired by choosing a certain bounty mission at some point in the story. ([], at the bottom.) So, can you only pick one of those? Or is it possible to somehow do all of them? Because I don't want to pick one and never be able to get the other weapons afterwards.
