Their using invisible(confirm) and auto-aim(maybe). When I (a lone wolf) just arrive Northwest airport I noticed their bandwidth are similar with me.So I ready my weapon and crouch in a bunker(just northwest out side the wall around the airport,next to the military camp). Then they noticed me with the bandwidth and start searching me (bandwidth sync fast!) I decide crouch in the bunker and hit'em in the head,but when the bandwidth are exactly the same I could not see anybody with my 3rd view,I suddenly realize maybe they are hacker and decide flee to the northwest forest,unfortunately when I run with a zig-zag route and they spot(I think they don't spot me when I crouch in the bunker, I should not came out) and one shoot kill me.I don't see them from begin to the end even with the lowest FOV and I'm in the f***ing sniper-nightmare northwest airport! I got 70ms ping and never a desync problem(thanks for excellent VPN) when I join this server so I'm pretty sure they are hacker. http://www.gametracker.com/player/katu/173.199.82.101:2302/ http://www.gametracker.com/player/expc/173.199.82.101:2302/ Please tell me how to upload img :) and why all HK and my clan servers are down
