Part 62

Follow this Ninja Gaiden walkthrough to find the Key of the Decayed Soul, defeat enemies in The Core, and prepare for the final boss battles in the Imperial Palace.

Use Ultimate Techniques (UTs) on the Crab Fiend. Once they are dead, approach the chest in the far-off corner to get a Devil Elixir.

OBJECTIVE: FIND THE KEY OF THE DECAYED SOUL

AREA: PALACE COMPOUND

If you take the whirligig path to the Imperial Palace, the door will be locked. To get the Key to open it, go back to the path and head towards the large gateway. When you reach the gateway, you will be swarmed by Ghost Fish. Bust out the Flails and start slicing away to get some essence. Once that's done, open the doorway to trigger a cutscene.

AREA: STAIRWAY TO THE IMPERIAL PALACE

After the cutscene, search the dead body for an additional item. Before you do anything else, there are a few more things you can do in Tairon before entering the Palace.

LIFE OF THE GODS #43
The very last piece of this item is located back at Great Bridge Square in the building that Rachel cracked open. Go into that building and then use a Wall-To-Wall Run to the top ledge to find a Life OTG (On The Ground)!

There is also ONE more Enemy Ambush to pursue in the game. The Prize for completing it isn't so hot, but if you're up for the Karma Points, then get to it and complete it!

ENEMY AMBUSH: GREAT BRIDGE SQUARE
HARD MODE NOTE: 80 RED DINOS AND OGRES TOTAL

If you need to go to Muramasa's Shop, do it now! Replenish all your stock before heading into the Imperial Palace! When you're ready, head back to the Imperial Palace entrance and enter with the Decayed Key.

AREA: THE CORE - 1ST FLOOR

A couple of Catwomen will appear here. Use hard combos and Explosive Arrows to kill them off. When all the enemies are dead, approach the mantle and place the WOLF DEITY statue. Exit out through the adjacent door and equip the Flails.

LIFE OF THE GODS #44
Slice all of the Ghost Fish here and then ascend the stairway to the next floor. Open the nearby chest for a Life OTG and then enter the next doorway.

AREA: THE CORE - 2ND FLOOR

This floor contains Arioch Crabs and Zombie Soldiers. Use wall attacks to decapitate the soldiers and use UTs on the Crabs to kill them all. Once that's done, place the DEMON DEITY statue on the mantle and then exit the room. Equip the Flails and kill more Fish!

AREA: THE CORE - 3RD FLOOR

In this room, you'll face off against Ogres. Use hard Dabilahro combos on them to kill them all. When the room is cleared, place the SERPENT DEITY statue on the mantle and then exit through the adjacent door. Slice some more Fish with the Flails and ascend to the fourth floor but DO NOT ENTER YET!

GOLDEN SCARAB #50/LIFE OF THE GODS #45
The last Scarab of the game is just below the fourth floor. When you reach the fourth floor doorway entrance, jump off the nearby ledge to land on a smaller ledge below. The Scarab is at the other end of the ledge, so GRAB IT! Now go back to the fourth floor entrance and open the chest to find the final Life OTG.

AREA: THE CORE - 4TH FLOOR

In this room, it'll be a split combination of Ogres and Crab fiends. Equip the True Dragon Sword and focus on killing the Crab Fiends first. Use hard combos and Flying Swallows on them to kill them. For the Ogres, use UTs from the Dabilahro or Unlabored Flawlessness.

Once the room is cleared, place the RAPTOR DIETY statue on the mantle to clear the entire Core. Exit through the adjacent door and slice the Ghost Fish in the stairway.

AREA: THE IMPERIAL PALACE CORE

Take the stairs to the top of the Imperial Palace. You'll find two chests, a Save Point, and a TEAM NINJA logo up on this floor. One of the chests contains Ghost Fish, so open at your own risk!

Before you approach the portal, SAVE your game! If you need to go back to Muramasa's Shop, you'll have to traverse all the way back down the Core. The closest shop is the one in Tairon, so go there now if you need to! When you're ready, enter the portal for an epic battle.

AREA: HELLISH DEPTHS

When the battle begins, Catwomen will appear and swarm you. Use evasive rolls and hard combos to clear the area. Once it's cleared, you will be transported to a boss battle.

HARD MODE NOTE: Hydracubus will have Pincer fiends assisting him. For the Yotunfrau battle, he fights solo.

BOSS BATTLE: MARBUS
HARD MODE NOTE: Marbus will have Kiyatts assisting him.

AREA: THE IMPERIAL PALACE CORE

With the DEMON DEITY statue in hand, place it on the mantle across the Save Point to open the doors above the Core. SAVE your game and finish whatever it is you need to do. If you need to finish the rest of the Enemy Ambushes you missed or restock at Muramasa's Shop, do it now! Once you enter through the doors above the Core, there's no going back! When you're ready, go up the stairs until a cutscene is triggered.

BOSS BATTLE: THE EMPEROR - FORM 1
HARD MODE NOTE: No changes in Hard Mode.

BOSS BATTLE: THE EMPEROR - FORM 2
HARD MODE NOTE: No changes in Hard Mode.

MISSION COMPLETE!
