Original Ninja Gaiden mini-game
Give 50 Scarabs to Muramasa to unlock the original Ninja Gaiden game. This does not have to be done in a single game play-through. You can continue from a completed game save and collect the Scarabs that were originally missed until you have the required 50 Scarabs. After giving them to Muramasa, you will get the Ninja Gaiden disc to be used at the arcade machine at Han's Bar's first floor.

Then go to the Clock Tower Plaza of Tairon. Get on the ledge above the multicolored door that leads to Pleasure Street (where you flip the switch to unlock that door). Aim your bow at the clock tower across the street. Shoot the face of the clock and a treasure chest will appear on the building that is across the street. Jump down, and enter the doorway across the street with the stairs. Climb to the top, and open the chest to unlock the Ninja Gaiden 2 disc.
Original Ninja Gaiden 3: The Ancient Ship Of Doom mini game

Go to the Peristyle Passage (the ceremonial room in the Aqueducts, just before the Boss fight with the giant fossil bird). It is next to the Hall of Balance. Triangle Jump back up to the top of the broken pillar where a Scarab was previously hidden. You will now find the disc for Ninja Gaiden 3 at that location.
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.

Armlet Of Tranquillity
Give 40 Scarabs to Muramasa to unlock the Armlet Of Tranquillity.
Dark Dragon Blade
Successfully complete the game on any difficulty setting. Start an already completed game and kill anything in your path. The more people that you kill, the more likely you will get the Dark Dragon Blade. When you reach the part to upgrade your Dragon Sword to the final level, jump into the open house and stay on the top level. The Dark Dragon Blade should now be into the ground, ready for you to unleash its power.
Healing Bracelet
Give 40 Scarabs to the shopkeeper for a healing bracelet that will slowly replenish your health. If you do not care about time, you can just stand in a no enemy area and just heal away.
Life of the Gods

Sprit of the Devils
Give 10 Scarabs to Muramasa to unlock the Sprit of the Devils.
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.
War Hammer
After defeating the flying female Boss that breaks through the stained glass, immediately when you start the next level run back into the doors. Go past all the debris and you can find the War Hammer in the area where you fought the Boss.
Windmill Shuruken
Go to Han's bar but do not go in the front of the club. There is an alley that has blue striped walls. Run on these blue stripes and it should lead you to a platform with an silver Xbox that replenishes your health and a metal plate that holds the Windmill Shuruken.
In-game reset
While playing a game, press Start + Back to return to the main menu.
Special attack
Press Y + B to unleash a super attack that will seriously hurt anyone.
Kill enemies quickly
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.
Finishing kill
While a foe is on the ground, walk up to it and press Y. This will instantly kill almost any foe.
Less battle damage
When you are grabbed by an enemy or a Boss such as the Dragon, mash the buttons quickly to escape without taking full damage.
Longer wall running
When you are about to fall from wall running too far, jump forward towards the wall again. You will start to wall run again.
Easy Essence
Killing a foe without using Y will give you five times more Essence. Also in Chapters 6 and 7, you will encounter the skeleton dino Boss. After you defeat him, climb down towards the new opening he made in the floor, but stop at the save location. Turn around with your Nunchakun and jump up to the bats. Once you reach them, kill no more than two to four bats and charge your super attack taking in two Essence Orbs. Then, unleash the attack and gather up to 2,000 Essence each time. To replenish the bats, jump back to the save point and repeat. The bats will not hurt you enough to kill, and will randomly give you health. Once you gather all the Essence desired, you can whatever desired. The maximum amount of Essence that can be held is 99,999.
More items
Do not pass up the dead ninjas that are lying around. They have items on them.
Obtaining rewards
Talk to the shopkeeper every time you see him. This is when he will collect your Golden Scarabs. He will give you rewards after every several Scarabs.
Unlock safe in monk's room
To unlock the safe in the monk's room for the first time you need to enter this combination: press Analog-Stick Left until you reach "2", then press X. 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. If done correctly, each time you press X a blue light should turn on, until you see four blue lights and the elevator to the underground cemetery opens. The combination is the Monk's birthday as he states in the diary (27th day on the 12th month). You can now get the Book Of The Eons from the safe.
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.
Defeating Doku
Keep using the Flying Swallow attack (A towards the enemy, then Y). Every time you hit him, roll back, then jump. After that, try the Electric Ninpo attack. Then, repeat the process. If Doku keeps blocking the Flying Swallow attack, keep attacking him with it until it hits him. When he throws his sword, you can either jump over it, or roll and jump backwards. When he is doing his combo attack, attack him when he is at the last attack of his combo.
Defeating Spirit Doku
To defeat Doku the second time you fight him quickly and without getting hit, simply use the Ninpo attack "The Art Of The Inferno". If it is level 3, you can kill him in about six hits.
Defeating the Dragon Boss
To defeat him, try to level up your Lightning Ninpo to the maximum. Constantly run left or right. When he flaps his wings you will take a little block damage. The only way to hit him without getting in the lava is to hit his head when he lays it down momentarily. Try using the Flying Air Dash attack. He will try to grab you immediately afterwards; throw in a Ninpo just after that attack. If you need to use a Great Devil Elixer, it will be useful.
Defeating Spirit Piranha
These enemies can kill you very quickly and are extremely difficult to get away from. They tend to leave a high amount of red Ki orbs. Simply use the Fire Wheels Ninpo and run through them. You should get enough red orbs to replenish your Ki. Also, use the Bracelet that enhances the red orbs.
Defeating Worms
You will fight several of these Worms. They can be cheap if you do not know what to do. Using the Whirlwind Shiruken is the key. Throw out a maximum of three when they appear from the holes, then block or dodge. Repeat this for an easy victory.
Defeating Zombies
Use the diving Y attack that takes off their head. It will not kill them, but they will be blind. Also, when facing the zombies under the cathedral and one of them happen to lunge at you and starts biting, press X + A as quickly as possible to kick it off and reduce the amount of damage that you receive.
