The mode also serves the purpose of training players for competitive online play who haven’t experienced it yet.The game will feature a currency called COD points that you can spend to unlock weapons. These are like expendable experience points that you earn just by playing the game.

They come in three flavours: Mercenaries, Operations and Specialist. The titles defining the play style required to fulfill the contract, apparently.Official Wager match video:Weapon customizations!
