Hint: Shooting difficult to hit far away
Look at the enemy through binoculars. Center the enemy in your
binocular sights, then switch back to your rifle. The rifle will
now be trained on the enemy. Fire a three round burst and you
will usually take him out. Rchyrch
Hint: Sniper rifle:
Always use a snipers rifle. This seems to work the best, because
you can stay low and pick your targets. If it gets too hot, send
your team. If you tell them to spread out, it works better than
an attack. gorreaver.
