Hype, notice I said Stalking, not laying for hours. Just slow painful movement as you follow or track a sniper team. Also, you can kit out to be a CS or a Tac Marksman, but that dosen't have to be the role you play at every game. Kit wise its only a 400 FPS AEG with some sort of Optics (this isn't even necesary), so really your options are limitless.
Maybe you'll find someone else to help you. Maybe black mesa... THAT WAS A JOKE, ha ha, fat chance.
