you can go around with a sniper rifle on your back and try to take down your enemies before they see you, or you can go in with an assault rifle, or an SMG, or a plasma rifle, or a laser rifle for that matter. Fallout: New Vegas is a game that can be played in every way: you could play though the main story and call it a day, or you could be a completionist like me and try to milk it for all it's worth over several separate playthoughs.
