To kill an enemy very fast, jump towards them fairly close using A, then quickly tap Y immediately before you hit them. You should either throw them with the guillotine throw or slice their heads off. If they keep trying to get off the ground, tap Y again to pin them down or cut their head off. This is useful when you need some extra money, are almost dead, or when you just simply want to get through the section quickly because of frustration.

Easy Ninja Gaiden 2/3 Trilogy Games
After getting access to Ninja Gaiden, play the game on very hard. When on Chapter 4 and you're in the Clock Tower Plaza you will see a door with a pink jewled eye. Above it will be a platform with a chest. Make you way up to the chest. Once there turn around and you should see the Clock Tower. Shoot the face of the clock with your arrows and another chest should appear next to you. Open to find (Ninja Gaiden 2: The Dark Sword of Chaos). Ninja Gaiden 3: The Ancient Ship of Doom is in Chapter 10. Once you enter the Hall of Balance. Enter the door (not the one behind the waterfall) and when you get into the room run to the right and inbetween the two podeums do a Flying Bird Flip to reach the top. There you will find Ninja Gaiden 3 rather than the previous Scarab that was there. Whoever said you had to get Master Ninja in every level should have wished they known this !
Easy Boss #1
The first boss you come to which is murai. You can't really attack head on. So go to one of the walls and face the wall and wait for murai to get close. Then do a wall run straight up the wall bye pressing A and then holding up on the anlog stick. Once you are above his head press A to jump off the and right after jumping off press X to deliver an attack to murai. Then as soon you reach the ground roll away. This won't always hit murai he'll dodge it sometimes. But the attack will hit about 70% of the time. Just keep repeating this process for an easy win.
How to beat 2nd boss
To beat the second boss you need the art of the inferno. Your just run up to him and jump and press y to stab down at him and keep repeating the Art of Inferno. The Art of Inferno should be equipped if not equipped, or it could equip automatically. Now you have to chop him up a little bit more until you beat him.
Breathe Underwater
Approach a large body of water and just as you hit it tap A to run on the water. Keep running until you hit a wall and start sinking slowly. Eventually you will hit the bottom and if you keep running you will be able to breathe underwater.
Run on Water
Anywhere there is water, simply walk Ryu onto the water and then repeatedly tap the A button to run across the water.
Play Japanese Versions of Classic Ninja Gaiden Games
Put the Text and Subtitles to Japanese from the Options menu, and you can play the Japanese versions of the first 3 classic Ninja Gaiden games "Ninja Ryukenden".
Kill Rachel
This is a neat little thing I found. It turns out that you can kill Rachel when she's hanging above the pyramid before Alma V2, or in the volcano cave before Evil Murai. Just shoot her with an arrow and you'll get a game over.
Retain Health with Kitetsu
While using the Kitetsu sword, equip the Tranquility Bracelet--earned by finding 40 scarabs--to counter the health drain effect of the sword.
Easy Cash
Did this at the Clocktower in Tairon, but I'm sure it should work at any store. Simply go up the set of stairs marked by the blue border, and take care of the three enemies in the stairway. Now, go back down the stairs and return back up to kill the same three guys again. Collect the loot or health and repeat as desired! I found that if you use the Nunchaku, you can score around 30 or 40 hit combos, giving you up to 1,000 cash points at a time.

Beat level three boss
Some players tend to have trouble with this boss mainly because of his massive power on attacks. Basically, he's equipped with a gigantic electric gun, that shoots out blasts of electrical charges in small intervals. What you should do is keep distance between him and yourself. Keep running in circles, but DO NOT jump (makes you an easier target). You can try rolling, but keep running in circles until he fires about 5 laser blasts. Suddenly, his gun will discharge, and it'll be jammed for a few seconds. Quickly sprint in, and lay down a few power slashes. If you want, you can also cast Ninpo magic to assist in causing more damage. Just repeat this strategy, and keep retreating/approaching. If you stay close too long, he'll grab you, and shoot you point blank with the weapon. Also, try to keep several potions on hand when facing him. You might take a few hard hits along the way. Aside from that though, he's not as challenging when compared to other bosses faced.
Evil Ryu
Complete the game on Very Hard.
Futuristic Outfit
Complete the game on Normal or Hard difficulty and start a new game while holding L.
Bat cash
This is pretty simple. In chapter 6 once you get under the monastery. There's cave that has a very large number of bats in. Now the first time you are in the cave there these wierd red flying mutants. But after you beat the skeletal dragon. you'll see him in a frozen state. Anyways after you beat him. That cave becomes full of bats. Have your normal shuriken equiped. Kill two bats with the shuriken. And then press and hold the Y button to asorb the two yellow essence into ryu sword. After you have asorbed the two essence into ryu's sword release the Y button to deliver ryu's ultimate attack. This results into each bat leaving a huge yellow essence gather them. Leave the cave then enter the cave again. Then this trick all again. Keep repeating this trick for about an hour and your will reach the max cash ryu can carry witch is 99,999.
Bat cash 2
Found another spot that you can do the bat cash trick. In chapter 12 there's an entrance to a bat cave that is hidden by a waterfall and on the other side of pool of water. To get to the cave look for three large stone heads and there's a save point to the left of the stone heads. Follow the stone heads to the pool of water and you will see the waterfall that is hiddening the entrance to the bat cave. Go through the waterfall and you be in a short tunnel and at the end is the bat cave. Jump down to the bat cave floor. Then start doing the bat cash by having your normal shuriken equiped. Kill two bats with the shuriken. And then press and hold the Y button to asorb the two yellow essence into ryu's sword. After you have asorbed the two essence into ryu's sword release the Y button to deliver ryu's ultimate attack. This results into each bat leaving a huge yellow essence gather them. This time around you do the trick probably 3 or 4 times before exiting the cave since this cave has a lot more bats in it. To exit do a wall run where you see the hole. Once back in the tunnel go to the waterfall and then turn around at the waterfall and head back to the cave and it will be filled with backs once more. And repeat this trick for about an hour and you will have the max cash the ryu can carry which is 99,999.
Skip to Final Boss on level 16
On level 16, get to the boss, and lose to him. Now, continue, and get to the Dark Dragon Blade. During the cutscene when you get it, press start, and the cutscene where you go to the final boss will play.
Dabilahro Sword
Give 20 Scarabs to Muramasa. Note: In successive mode you do not get it again until you give 43 Scarabs to Muramasa.
Unlabored Flawlessness
Upgrade the wooden sword completely to receive its true form, the Unlabored Flawlessness. It is a large weapon which you swing like the war hammer and Dabilahro, and has a very powerful Ki attack. This weapon makes Boss fights easy.
Playing classic games easier
Instead of going to the first floor of Han's Bar, use the following trick to start the games from the main menu. Successfully complete the main game while any classic Ninja Gaiden disc is in Ryu's inventory. This will unlock another main menu option that will allow you to play the classic games from there, without going to Han's Bar.
Defeating Alma
To defeat Alma (red greater fiend), equip the Vigorian Flails. It is recommended that they be completely leveled up. With the Vigorian Flail, you can still hurt Alma greatly even when she is in the air. Note: The shuriken, incendiary shuriken, and bow cannot hurt her; they just bounce off.
Defeating Black Spider Ninjas
Jump off the wall and use the X attack to smash down on top off them. Use this repeatedly, but be careful of the incendiary shurikens that they throw.
Unlock safe in monk's room

Press Analog-stick Right until "7", then press X. Press Analog-stick Right until "1", then press X. Press Analog-stick Left until "2", then press X.

Boss number 2 made easy
This way is much easier then using nimpo, he might look tough but he is owned by the bow, make sure that you have the bow in your inventory (kindly donated by a dead ninja)and the max of 15 arrows ( pick these up from the dead ninja in the clearing where you fight the three samurai warriors ) when you confront him pump him with all 15 arrows and this will take most of his life then just go for the kill, N.B if you find yourself short of life then just kill his little floaty friends to get blue eccence.
Special Shurikan
To the left of Han's Bar there is an alleyway and when you walk towards it Ayane will throw a note which reads something like "i have hidden a special weapon down a alley where only a ninja can reach", if you look up you will see the blue stripes, do a continuous wall run around the corner and jump onto the ledge (might take a couple of tries) you will find a weird xbox type of machine that will heal you and your nimpo completley, also there is a 4 bladed shurikan that when thrown returns like a boomerang.
Defeat Samurai horsemen easily
In the Hayabusa ninja village you will encounter some annoying horsemen. To easily dispose of them, just use the Inferno ninpo(gained in Muramasa's shop)One blast of Inferno will throw them off their horse, making it easy to dispatch of them.
