Long RangeG 10

This achievement requires you to kill 20 enemies with the available sniper rifle. You will pick up the rifle very early in the first level.

Simply use the rifle and aim for the head or torso and get a kill. Repeat 19 more times. I found it obviously easier to do this on the easier difficulty level - make sure that you do have adequate cover as you aim.

The achievement should unlock on your 20th kill using the weapon.

I earned this achievement in the first level - there are more then enough enemies to kill. Also, if you are having difficulties, make sure you enable 'Aim Assist' in the options menu.

Any questions, feel free to message me.
