Was just returning after the turmoil of starting back up a new semester, and with a fresh BO2 CD, I noticed that you can't purchase it anymore; why is that?

Also, just curious. I know that the BF3 and a few other cheats dont have the Human Aim / Slow Aim (slows aim speed, or makes it more fluid instead of snapping), but does this one? And if not, would implementation be looked at?

Danke!
