One Flag CTF is poised to make an appearance on Call of Duty: Black Ops 2. The new mode was revealed during an MLG livestream, where MLG Puckett announced that the mode would be getting added. It will be separate for all maps, and will be made available in an update to the game this week.
One Flag CTF is a lot like regular capture-the-flag, except there's only one flag on the map for both teams to fight over. It appears in the center of the map and turns the area into a hotly contested zone as both teams vie to take control over the flag and bring it back to their home base.
