Guide: Sniping is more of a fishing game sometimes in 1 spot you can get 30 kills sometimes you get none. After you get used to making a +30 head shot kill streak you can implement moving into ridiculous hiding area's. Being unexpected is good such as hiding behind the ruins in Paradise Island 2 instead of hiding inside the ruins, not only is it a good hiding spot it provides tree coverage and you can easily spot 2 respawn points.
Many people have a misunderstanding of sniping being used with pursing a person because when you see a person who takes a sniper out to take someone their chasing you can easily take out this person since they are traveling in a straight line. I use my teammates for decoys when it comes to finding another sniper, since bullets can be seen; I then use a counter measure by hiding in a hidden spot from the sniper.
Author Notes: Yes this is another reading guide that is poorly organized but I'm no peer editor. My theory behind sniping is: "The perfect sniper can be completely invisible, and if you can see your target he won't be able to see you". I have yet to perfect this theory but getting 49-0 with only a sniper is very good.
