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.
Treyarch confirmed that the Zombies mode would return for Black Ops II with new game modes. Its predecessors were Call of Duty: World at War and Call of Duty: Black Ops. This is the third time for the Zombies mode to appear in a Call of Duty game, and the first time to have game modes other than the traditional Survival mode. Treyarch also confirmed that Zombies would run on the game’s multiplayer engine, allowing for a deeper community experience, along with new features. A new, 8 player co-op game called “Grief” is also supported, featuring 2 teams of 4 players competing to survive, unlike Call of Duty: World at War and Call of Duty: Black Ops, which only supported 4 player online co-op. As with the previous game, each map contains “Easter eggs” side quests, which is used to progress the story. Another form of Zombies mode is called TranZit, in which up to 4 players travel around different maps and collect information that would show the players what lies ahead of what they are willing to discover.
