[..YouTube..] I agree with halo covenent you only need about 50 knocks then all of the sudden It screams and it scared the hell out of me I nearly had a heart attack
[..YouTube..] oh really?
was it like those videos when ur just watching it and then some scary faced pops up screaming at your face?
[..YouTube..] and if you knock on it like100 times the screen would just break and yes it was scary cuz my hand was bleeding. I found that out the hard way.
