A new enemy has appeared in the galaxy and is presenting a threat to humankind on par with the Reaper that Shepard defeated in the first game. Things have gotten so bad that Shepard was thought to have died in combat. Fortunately, he was rescued and recruited by a shadowy underground group who is looking for his help on a suicide mission. Shepard is the only human capable of pulling off this mission successfully, but he can't do it alone. Instead, he'll have to recruit the absolute best the galaxy has to offer to aid him in his quest, à la 'Ocean's 11.'"
