I do love the calamity of Shipment, the old Shipment was smaller and better for it I think, absolute carnage. It is hard work levelling up but I have no interest in levelling up the shield.
I haven't got the M13B yet but a friend did so I need to log on with him and extract after he gives it to me but I don't really like DMZ or Warzone, just like multiplayer, particularly Search & Destroy.
