Hi guys.... I read all the posts and I decided to set a couple of things right... First of all ... bullets from sniper rifles that are in game (Cz 550, M24, dragunov etc.) they all travel appoximatelly 800m/s (not 300 as mentiond in some pervious replays). Secondly, how to find right distance? Well on regular difficultly it super easy ... game directly tells you haw far away other player is. ON veteran and expert... well using map tiles is good idea, however it takes quite a long time that you usually don't have. So instead practice to measure the according to how big your target is compared to that scope trangle... it takes some practice but it's quite easy. Moreover ... always zero TO LESS THAN WHAT YOU THINK THE DISTANCE IS and aim for the head... this way you hid a headshot if you got the distacnce correctly and if you didn't youll still hid him and can shot him second time to kill. Next thing is how to hit a moving target, that's a bit tricky ... did you ever wondered why is there a horizontal scale on the scope? well I experimentaly confirmed that if person is moving perpendiculary to your aim in crouched run you have to aim 3/4 of one of that horizontal scale tiles in front of him ON CZ 550, don't have any experience with better rifles.. AND importatn thing .. this doesn't change with distance... way the mathematics of this calculus works is distance independent! so if a target is 200m in front of you an is crouchrunning aim 3/4 in front ... if he's 500m away crouchrunning aim the same 3/4 in front of him !!! Always watch a target first and confirm weather he's alone or not, wait until you have a clear shot, you only have one shot to get him down!! If there are zombies around your target or you keep in mind that after you shoot you will have to run !! Have some indoors ready to run to and take care of zombies, that are chaising you there. It's always better to let go of your target if you're not sure you will hid him with first shot !! And btw... after you kill someone ... and he asks in global who it was... there's nothing better than to admit is was you along with some smart coment like ... "I just taught you not to run with flare in your hand" And keep posting interesting strategies guys... finally some thread for real sneaky players :-) :-)
