Its supposed to be realistic.. can be hard

i dont know about help but a few tips. Play hardcore 1 shot kill everytime.. get good at staying in one spot with little to no movement. stay along the edges of maps... get to spot using the out of bounds timer, this can get you to some nice sniping spots.

far distance snipes aim above your target,..
runners in front of your target..

if you play regular it usally takes 2 shots unless you get a headshot, or lucky with the right setup.
play hardcore, you will find 75% of the people playing are sniping,.

Depends, do you play core or hardcore?

Playing Hardcore would mean that you can kill easier, however you will get killed easier.

I was thinking more of the lines of what to use ect.
and the crosshairs

again depends on gametype.

hardcore any rifle is good, the GOL has very little drop. If you are good at head shots use the auto sniper.

Regular same thing, but the auto rifle is horrible.
the 50cal is really good in non harcore.

and i always use 12x zoom, unless i play conquest (next to never) i switch to the 4x alot more close battle combat.

Just aim a bit over the Head for a Headshot cuz Gravity pulls down the bullet.

Its a terrible game, play pokemon instead.

Well, start doing hardcore sniping, use steady aim pro and don't worry about getting a headshot each time.
