ps there is also a bonse evolution after the dog rounds evolution so yes to everyone hellhounds were in black ops 2 zombies but they had to be added in so offically they were not in any of the main maps just the survival areas but other then that the hellhound rounds did not change much just the design of the dogs was pretty much that so if you guys love these evoloution videos i did have three more i can think of so thanks for watching
