As a ninja, superb swordsmanship and fancy positioning are necessary.In the game, you need to use positioning, your body and knife skills to play.Living as a ninja ,obviously,you need to kill enermies with silence.If you don't want to be found by your enermies,the only way is to wipe out all of them.Our approach is that if one knife can defeat the enermy, there will be not a second knife.Stopping will only blunt your knife.
