How to unlock

This is where the last chakra fragment is hidden

To unlock the famous battle between Kabuto and Uchiha brothers, you have to first finish the

story line. This will unlock a so-called Free Mode, which allows you to wander around the game

world.

Go towards Hokage's Mansion and you will see a frog at the bottom of the stairs. It will give you

a gem which puts the locations of chakra fragments on your map. One fragment gives you 20

points. Once you have collected 5000 points (the maximum), go back to the quest giver and talk

to it until it asks you to bring yet another fragment. You will find this where the final fight of the

story line had been fought.

This is a clearing with a black stone at the center. On picking it you will face Sasuke - what you

have to do is kill off the white Zetsu, and finish the fight with beating Tobi. You should not have

any problems with that, especially after finishing the story line.

Once you have beaten him, you will unlock Kabuto fight in fights tab.

The fight

The fight against Kabuto is the toughest battle against an AI there is.

It is good to eat Bento before this and set the Hero equipment so it contained as many health

potions as possible.

In the first phase you play as Sasuke - this is not particularly difficult. Do not use the potions,

even if you receive some serious damage, because in the next phase your character is going to

switch for Sasuke's brother. Once you have significantly weakened your opponent (two and a

half bars) a quick time event will initiate, after which you will be playing as Itachi.

This is where the problem starts. The enemy is extremely aggressive, has five health bars and is

very resilient for your attacks.

While fighting you can notice that charging at you makes your opponent vulnerable. When he is

doing that, wait a moment and once the distance between you two is right, throw the Ultimate

Jutsu at him, so to deal him as much damage as possible (you may also use counter-attack).

Use Sasuke as often as you can, so to increase the damage you deal.

Kabuto often uses the Snake Mode, so you need to keep up with him or to use support and

ninjutsu interchangeably - it often happens that Kabuto uses the Substitution Jutsu on one, but

gets hit by the other. This is when you can charge your chakra.

An end to a breathless fight

The key thing is to avoid direct combat, unless you have all four body replacements ready,

because otherwise Kabuto's combo can take a lot of your health. It is a good idea to knock him

up into the air, jump to him, and punch him a few times while he is defenseless. You should best

count how many times he has used his transformation skill - once he has used it four times,

attack him with full combo.

Two bars down and Kabuto jumps at a rock. Then, the only way you can hurt him is your

ninjutsu. If you have not lost too much health and have not used any health potion at this point,

you are on a straights road to victory.

When a Secret Action notification appears, Kabuto freezes for a moment. You can either use

Chakra Dash to initiate a cut-scene or walk toward him and cast the Ultimate Jutsu. He cannot

defend himself at the moment.

Be careful though, because initially Kabuto summons Kimimaro's spears and performs three

quick attacks. You can use Substitution Jutsu or double-jump to avoid these. When he jumps up

on the rock for the second time, he throws rocks at you and then casts a spear.

He will jump up there several times and when on elevated position, he will be using nets and,

finally, ghosts. All these attacks can be avoided with substitution-jutsu or double jump.

When his health is low he uses all the previous attacks and do that even more frequently than

before. Moving rocks can be destroyed with ninjutsu or support's attack.

The fight goes on until you reduce Kabuto's last health bar to zero. When Itachi activates Izanami

the fight is over.
