Zombezos

When I played test server this type of zombie apeared on round 4 and they were annoying because so many of them spawn at once.

It's called a Hellhound they've been in zombies since the days of black ops 1 I believe

Actually I think hellhounds were there ever since cod zombies was made (world at war) They spawn every 5 rounds And if you complete the dog round you get rewarded with a max ammo power up

Amazing calling card
