Theres a lot of things you definitely should not try to solo, especially the special missions, one of which is a rematch. one is 6 jumpers, one is six Grey Lotuses, so far. and one is a partially rebuilt Spirit of Motherwill. Edit: and by solo, I mean you as the only human, UNACs be damned, they don't count for shit in these missions. http://www.youtube.com/watch?v=SwUYIEFhAsY
