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 Marksman; friendly fire is on (you get hurt if your co-op partner shoots you), you take even more damage when shot and enemy AI is very smart, more aggressive, stay alert longer and even harder to kill than on the lower difficulties. Also, there is considerable bullet drop, so use and to adjust the range of your scope to the distance of the target. Crosswinds play an even bigger factor on this difficulty so aim to the left or right to account for wind (wind gauge is above your crosshairs).

It is recommended that you play as stealthily as possible, use suppressed ammo and sound masking and only kill when required.
