Who said we stumble? We glide silently like a fleeting shadow. Our super ninja stealth allows us to pass enemies unnoticed and we approach our prey with almost no sound. A tiny creak as the slingshot rubber is pulled back, a quiet thunk as the smooth round stone kills our prey and then we return to our lair for lunch.
Actually, we can hunt while you are asleep which is most of the time.
Really it shoud read, "go ahead, stumble around all night, trying to score with a pos CAR. It will just make you a LOT easier to detect and shoot with all that stumbling and losing you way in the dark forrest. Even when you shoot, the sound of the bolt slapping back and forth, brass hitting bushes, supersonic crack will be heard well past the 25 yards you can SEE. Stupidity like that SHOULD be fatal."
