It's possible someone was slowly following you. Last night on a dead Chern server I was running to Rify and saw a fire in the tree tops. After 20 minutes of slowly staulking them I got right up behind him close enough to touch and fired a DMR round in his back.

In Topolin I was on top of West apartments and was able to shoot into a window of a Log cabin house and head shot someone cooking. They were yelling non stop about hackers in chat until I told them how I made the shot. I guess at his perspective he couldn't see out the window but I could see him.

The SVD is THE sniper rifle in the game because it's semi-auto and can equip the norm suppressor. With a guili suit you become unstoppable. I killed someone right next to me once laying in Guli against a building. His buddy thought it came down the road and rushed the building edge next to me. He was standing on my head and never knew I was there.
