When the announcement for the Dark Below came out, it said that there were going to be three new story missions. When I hear story mission I think of a mission that is re-playable....I hope they don't count the short quest to kill the Fist of Crota, as this appears to be part of the Eris quest line... don't know if I missed something, but I have found only two actual missions you can do over again. One on Earth, and one on the Moon. Where is this third mission? If I am missing something, some one please point me in the right direction.
