Gun Game is a Wager Match game mode in Call of Duty: Black Ops, a private match custom game mode, and as a game mode in FFA Gunplay, in Call of Duty: Modern Warfare 3 as well as a game mode in Call of Duty: Modern Warfare 3: Defiance. The game consists of six players competing in a free-for-all-style game. Each player starts with a pistol; As players get more kills, the player will receive different weapons. Upon death by knife or suicide, the player goes down one weapon tier, but knife kills do not advance the killer to a new weapon. The first person to achieve a kill with all twenty (or 18 in MW3) weapon tiers wins. However, if the match ends without anyone getting a kill with all the weapons, the player on the highest weapon tier wins the match. Due to the fact that only 20 or 18 kills are needed to win, and the game is a Free For All, games are usually fairly short.
