nice!
WALKTHRU FOR LVL SIX: walk against wall right next to the guard (directly up) come off the wall and snap his neck fast! keep going to the next one (on his own) and do the same as the first! then go 3 step away from the corner towards the other guards and knock on wall, then go round away from them (not leaning against wall) then when he is not looking snap neck. then go against the wall and kill the other guard (as u did to the first and second guard)
****say is helpfull**** *thanks*
