Multiplayer and Warzone Unlock Challenge

In Multiplayer or Warzone, you will need to get some sneaky kills. Using a Melee weapon, you need to kill an enemy without receiving returning fire in 15 different completed matches. This means you will need to sneak up on them and take them out without taking any damage from them. You will also need to do it in a total of 15 matches, and you cannot leave those matches early once the challenge is complete for that particular match.

Zombies players have a very different challenge that they can complete. Using a primary Melee weapon, the need to earn 150 Butcher Medals (5 rapid Melee kills). This is not that hard to do, as you can have the zombies trail you until five of them are lined up, then rapidly melee them all down.
