Sniper Elite 4

This is story related and cannot be missed. This achievement is stackable is you play on a higher difficulty first. Refer to "Are You Insane?" for more information.

This difficulty is more difficult than Cadet; you take more damage when shot and enemy AI is smarter, more aggressive and harder to kill. Also, there is slight bullet drop, so use and to adjust the range of your scope to the distance of the target. Crosswinds play a factor as well so aim slightly to the left or right to account for wind (wind gauge is above your crosshairs).
