Distract an enemy.

This is very simple to do. Once you start playing the Goldfinger mission, you will eventually meet up with **** Galore and go into an elevator. Once you get out, you'll encounter a guy that's unsure of you and you'll immediately get into a fight. Follow the instructions and beat him up until he's dead, then continue to follow **** Galore. She'll see two men and ask you to find a way to distract them. That's when Tanner will instruct you to use your wristwatch on an acoustic device. In this case, it's one of three cameras, the first one you'll see directly in front of where **** Galore is standing, above her head on the wall above. Hold down the left trigger and aim it at the camera. If done correctly, you will see your reticle go red. While holding down the left trigger, hold down the right trigger and the wristwatch will begin its work on the camera. Once it's done, the enemies will be like "What was that?" or something like that. Just stay away from their view, hiding behind **** Galore. It will take a few seconds after destroying the camera and distracting the enemy for the achievement to unlock.
