Multiplayer and Warzone Unlock Challenge

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

Zombie Unlock Challenge

Zombie players have a very different challenge that they can complete. Using a primary melee weapon, you need to earn 150 Butcher Medals (5 quick melee kills). It's not that hard to do, as you can have the zombies follow you until five of them are lined up, then quickly take them all down in melee.
