death everyday!! live or die

I am playing a game call team factor. I like to be a sniper in the game and the reason is......... I always snipe and kill people with only 1 shot and is by shotting their heads. Once i was the only 1 left and i had to kill 6 other enemies and to make matters worse, i was a sniper and had a gun that take a long time to shoot . You think i am good at sniping but the bad part is that the stage i am playing is not a stage for sniping..HAHA. During the match i have to hide and wait for my enemies and slowly one by one the enemies walked past and i killed them in one shot on the head.
