Fast Hands returns in Call of Duty: Black Ops II. It lets the player swap or use weapons, grenades and equipment faster and safely throw back grenades.
Specifically, Fast Hands reduces weapon swap times by half, this ALSO includes switching between modes of fire with Select Fire , and decreases equipment use time by 40%. This applies to picking up weapons off the ground as well. Fast Hands allows players to pick up enemy frag grenades from further away, and resets the timer until they will explode to 2.5 seconds. One of its main uses is for tactical grenades, such as Flashbangs or Concussion Grenades, allowing them to be quickly used without leaving the player vulnerable for a particularly long time.
