While there are still hackers and other problems impacting the games, players have returned to the older Call of Duty titles in large numbers, with over 10,000 people currently enjoying Black Ops 2 multiplayer.

Call of Duty Black Ops 2 now uses the Multiplayer engine for Zombie Modes. It features new and extensive Stats-tracking, as well as improved Leaderboards for bragging rights. The new skill-based matchmaking system will allow players of the same skill levels to be teamed-up to fight Zombies in public game modes.
