In Order these are in ( my opinion ) 5 things zombies should have, Video coming soon!
1: Mic only option
2: Local only option for psn and xbl
3: Theatre Mode, Split into rounds 1-10 11-20 etc.
4: Differnt difficulties, So noobies can learn and hardcore zombies guys can have a challenge from level 1! (Not for xbl or psn)
5: Private match, Like in multiplayer. Where you can choose only guns from the wall, or only shotguns or no perks, etc. Also change zombies difficulty and even play gamemode like OITC or Infected! ( Really make playing more desirable when your bored of just regular zombies)
