Man I get so frusterated playing regular (not hardcore) modes. I don't know how many times I popped 5-6 rounds in to someone and then got killed by them with one shot. I was using a commando to. Not an under powered weapon at all. You were decimating everyone with that shotty!
Bring on the sound whores! Some guy set a sentry gun in that back building that everyone sets claymores at and fires out the window on Radiation. He had the sentry gun pointing out the window so I just crept up the stairs and m72'd the sh*t out of that thing and BAM! Ghost Pro!!!
