Not hard if you think about what your doing and actually use the "Z" to zoom in. I know people who blame it all on lag or their video card or something else stupid, but if you zoom in IT WILL DO YOU JUSTICE. Zooming in gives a little more better aim and it's better off knowing where the bullets actually go anyway.
yea i've tried both but seriously think AA is better game in every aspect even controll and i think the run is just perfect in AA but for now I seem to have a hard time coping to shoot moving enemies in mid to close range. it's like i constantly mis-judge! it sux!!!
