Is Call of Duty Black Ops multiplayer safe?

Yes, I don't see what's bad about it. But I disagree with the Zombies and Single-player. But multi-player I think is great fun and cool because it has no gore but tiny of blood.

Also: online play is safe. However some people may have modded their system with cheats but it will not mess up your xbox or make it malfunction. --Zman605
