@AugFC: The Original Crew traveled back in time to Shangri-La after the events of Call of the Dead, considering Moon came after Shangri-La, and Moon occured at the same time as Nuketown Zombies.

@"Fracture": True that the Original Crew got across through teleportation, I forgot to add that in. What I meant to say was that maybe, just a possibility, that Richtofen could transport them to earth, just like he did with the New Crew.
