Tenchu Z

In order to get this achievement you must complete all 50 missions on normal with a ninja 5 ranking (900 or more points). All of these missions on normal are easy, mission 16 being the hardest although still easy. completing a mission doesn't care over to the other difficulties so if your want all three of these (easy, normal, hard) achievements then you'll have to play 150 missions at least, which isn't that long as once you get good you'll be able to wrap missions up in 3-7mins with 900+ points.

The easiest way of getting 900 or more points is stealth kills, you get 100 points for normal sk's (stealth kills), 120 points for total sk's and 80 points for chokes then sk's. Patience is also key, be sure to notice enemy movements as there is always gaps for when you can strike.

You also get points for special objectives such as boss kills (sk's give you more points then normal kills) which vary depending on the boss, you'll get 100 points if you can survive the mission unharmed and another 100 points if you haven't used any weapons. If you stay undetected you get 150 points, make sure to use sk's effeciently especially from rooftops and also use your crouch when landing and moving around populated areas.

Avoid killing civileans which results in 300-400 negative points and detections which are minus 80 points each. Be sure to not stay in mayhem mode to long as well, as you'll lose minor points for that depending on how your long your in mayhem mode,
