3 buddies and myself were crossing a large field and we got a few zombies trailing. We didn't care much for them but then buddy1 asked if we should kill em. I said no as we would lose them anyway but I told him that if he wanted to, why not! I personnally hesitated to do so... Being full geared and all... So I kept running. He stopped and BAM! Buddy1 got sniped. Nobody had a snipe rifle at the time so we basically ran like headless chickens. I heard 6 or 7 bullets flying, the gunshots sounded like an M107... So I ran for cover, serpentine style, those few seconds seemed to be minutes.
