You know, iI think that Zombies is really getting away from the original point. Now it is less about surviving for as long as you can and more about completing long complicated easter eggs. Sure it can be fun to release two guys and get the focusing stone but that really isn't the original purpose. I miss the days of Der Riese and just surviving on the catwalk. Also they have tried to make things too complicated. Now their are shrieker zombies, napalm zombies and monkeys that steal power ups. In Call of the dead they added George Romero which pretty much makes camping impossible. In Shang-ri-la there are no good places to camp except on the stairs to the pack-a-puch or on the bridge with people covering each side. I just think that they need to get more to basics again.
