Another random achievement earnable in Clan Battles only. During the course of obtaining the other MP achievements you will undoubtedly be given a contract to perform a betrayal. Once this contract is given to you, walk next to any team member, click in and press . This will stab and kill that team member. At this point you will change teams, your previous team will be given the contract to kill you, and your new team will be tasked with protecting you. When you betray your team, all of your kills are deducted from your previous team's score and added to your new team's. Keep this in mind when going for the ten wins achievement. Online MP only!
