Double Trouble is a campaign achievement/trophy in Call of Duty: Black Ops that requires players to complete the mission "Numbers" using only dual wield weapons.

The player starts out with Dual Wield CZ75's, and can only use Dual Wield weapons. Enemies commonly drop Dual Wield Kiparis' (which can also be found in all the weapons caches). In the end of the level, the player pulls out a pistol that is not dual-wield, but if the player shoots the pistol, they can still unlock the achievement/trophy. Players can also use their knife or grenades to get kills and still earn it.
