One in the Chamber is an MW2 party mode where players have three lives but only one bullet in their pistol.
If you get an elimination with your single bullet, you will be granted another. However, if you miss your target and have no ammo left, you must get a melee kill to receive a bullet.
Each game of One in the Chamber will last until only one player stands alive, as the others have lost all three lives. However, the winner is the player who has gained the most score from kills throughout the match.
This mode is a free-for-all format meaning that it is every player for themselves.

How to Win in One in the Chamber MW2 Game Mode
To win in One in the Chamber, you must become the player with the most points from getting eliminations and surviving.
This makes it possible for a player to win the match without being one of the last players standing. Players will achieve 100 points for each kill and 10 points every time they are alive when someone loses all three lives.
