Hint: Stealth kills:
You can get the different stealth kills by being in the correct position in
relation to the enemy.
Easy stealth kills
Sneak up from behind.
Sneak up from behind and crouch.
Jump on enemy, while pressing Attack in mid-air.
Moderate stealth kills
Sneak from the side.
Hard stealth kills
Note: This must be timed perfectly. Sneak from front (or wait for them to turn
around into you).
Hint: Rikimaru's Stealth Kills:
Behind: Rikimaru slits the enemy's throat.
Behind while crouching: Rikimaru trips the enemy with his sword, then stabs him
in the chest.
Jump: Rikimaru stabs his sword into the right side of the guard's neck down
through the collarbone area; Rikimaru then uses his left hand to push the
guard's neck towards his sword causing the guard's neck to snap.
Hint: Easy kills:
Hitting an enemy who is not aware of your presence in the head with a blow gun
dart will automatically kill them.
Hint: New look:
Use the Ninja Armor to get a new outfit for your ninja. To get the Ninja Armor,
get Grand Master fifteen times. Note: You cannot use the Ninja Armor in the
mission editor.
Hint: Create a rooftop level:
Use the town tileset to make a rooftop level in the mission editor. Use pitfalls
and flat ground rooftops and put buildings close together to make it more
realistic. Power jump to get from building to building.
Hint: Shark in last level:
During the last level, go to the ship where you fight the first Boss. Go around
his ship to the right side (coming from the south side) and swim in the water
north/northeast to find a very big ship that towers above anything your
grappling hook can even touch. Swim around on this side of the ship for awhile.
Somewhere nearby a shark should appear in the water. The shark can hurt you, and
will put the enemies on alert as if he was a normal enemy.
Hint: Put away your weapon:
Quickly press Circle(2).
Glitch: Automatic stealth kill:
You do not need to pull out your weapons to perform a stealth kill. Run to the
enemy and press Attack. Your weapons will instantaneously be drawn out, and you
will perform the stealth kill.
Glitch: High jump:
If you are in certain levels (Quarantine Village, Laborers), you do not need a
grappling hook to get on to the roof of a house. Run up to the wall, face it,
and jump. Your character will jump twice the normal height of the usual jump and
land on top of the roof without hanging on the side.
