How to Get the 'Bullseye' Achievement in Battlefield 3

If you're crafty with a sniper rifle, this achievement is for you. In order to get 'Bullseye', you have to take out all of the bad guys in the level "Drop 'em Like Liquid" without alerting anyone to your presence. Good luck with that, by the way. If you manage to pull this off, you'll be rewarded with 20G on Xbox 360, or a bronze trophy on PlayStation 3.
