Eagle Eye

Eagle Eye is an achievement/trophy in the Chronicles Pack, a DLC for Metro Last Light.

Overview
This achievement is awarded for killing more Watchmen than Artyom in the level Anna. The sniper rifle Anna has will kill a Watchman in one hit, so line up your shots anywhere on the body and fire. There will be several waves of Watchmen, and killing about 8-9 of them is usually enough to unlock this achievement.
