Okay, we can all admit that Battlefield 3's single player campaign wasn't the best thing in the world. That doesn't mean that there aren't some good achievements to get from it!
In order to get the 'Ninjas' achievement, you have to reach the VIP in the level Exfiltration. Oh, forgot to mention, you have to do it without alerting a single guard.
Getting the 'Ninjas' achievement will net you 20G on Xbox 360, or a cool bronze trophy on PlayStation 3.
Unlock every achievement in every game.
