The Overwatch Sniper is a soldier in the Combine Overwatch, trained in the use of the Overwatch Sniper Rifle. Snipers are encountered hiding in high, concealed areas where they can get a good field of view. They are never seen holding their rifle but the blue transparent sighting beam emitting from it is. They can be detected by the beam or by the sound of the rifle firing on another target. Gameplay-wise, it succeeds the HECU Sniper featured in Half-Life.
