The Titans continue to climb the great mountain of the greek pantheon. Atreus looks up the kingdom as he sees Helios riding his chariot as he implies that the titans will fail again.

Atreus pulled out his blades of Valhalla and began to attack the undead warriors. All at the same time. Once it was done, Atreus runs forward to reach the wrist of Gaia as he summoned his wings he began to fly upwards to the mountain at high speeds.

Calliope leaps off the edge as she began to fly downward.

Both Atreus and Calliope see each other as they were flying towards one another, they get close as they threw a punch in sync with their left fists, their fists only slightly graze their left cheek. Atreus passed Calliope as she was now following him. Atreus flies to the left of side of the mountain to see the other titans being pulled out of the mountain as the volcano titan was trying to smash Helios, Calliope fires a energy blast at the volcano titan as it fell into the clouds as the little girl continued to follow her brother.

Atreus turned around to see Calliope catching up as he wings were still flapping backwards. Atreus used his illusions to create a mist to blind Calliope, Calliope covers her eyes as the mist cleared as Calliope looked in all directions to see that Atreus is gone. Calliope sighs in disbelief as she flies upward back to her parents and Zeus.

Atreus landed on top of the head of Gaia as Poseidon rose from the waters into his true god form.

"You challenge me mortal? A god of Olympus!" Poseidon shouts up to both Gaia and Atreus.

"A true warrior dosen't hide Poseidon! Leave the waters and fight me!" Atreus says.

"You will not be the destruction of Olympus, Atreus."

Poseidon casts his trident forward as he to command his minions to grab Gaia so that she cannot move, Atreus quickly punched Poseidon's minions for them to release Gaia as she delivered a strong punch to Poseidon's chest as Atreus flew to Poseidon's core to grab the Poseidon himself. Atreus flew at high speeds to send Poseidon himself at a wall. Atreus now walks forward to a weak Poseidon.

"No matter how many gods fall, there will always be another to stand against you."

"They will die as well."

"The death of Olympus means the death of us all Atreus."

"Then prepare for your death Poseidon."

Atreus grabbed the sea god by his throat to headbutt him in the face as blood splashed across Atreus's face. Atreus throws down some deadly punches to Poseidon's face. Atreus throws Poseidon to a edge of the mountain, Poseidon looks af Atreus walking towards him, the sea gods hands start to shake in fear as he tries to fall down to the edge to get away from the angry Scandinavian. Atreus grabbed Poseidon by the leg to pull him back as he snapped the sea god's neck. The dead sea deity fell over the edge of the mountain as fell into the ocean as it swallowed the lands. Atreus fly to Gaia's hand as both of them now arrive at the Dias. Atreus stepped on the Dias to see Zeus, Kratos, Lysandra, and Calliope.

Calliope walks forward to give Atreus a slapped to the face but he didn't even show any signs of pain in his face, he looks back at Calliope, "Good to see you too."

Kratos and Lysandra approached them.

"I could say the same for you, brother. Why lead an attack on Olympus, knowing your family is here?"

"Zeus killed me in cold blood as you were still asleep if you haven't noticed my scar. Zeus has deceived you, he is the father of Kratos who lead the curse on Callisto."

Kratos eyes widen in surprise as they all look back at Zeus. He looked at his fathervwjth murderous intent as he pulls out his blade of Athena. Atreus stepped forward.

"What will you do now, Zeus? You can't hide from the skirts of Athena anymore."

Zeus with his arms crossed, "Athena is dead because of the rage that consumes you, Atreus. What more will destroy?"

"The hands of Odin couldn't kill me, the sisters of fate could not hold me and you will not see the end of this day. I will have my revenge." Atreus says as he slowly pulls out the blades of Valhalla while Lysandra and Calliope readied themselves.

"I will tolerate your insolence no more!" Zeus shouts as he flew into the clouds and descended on his own statue as casted a thunder bolt to his hand and threw at the Dais sending everyone falling off of Olympus. Gaia was able to hang on to the side of the mountain at the others where falling to the underworld. Atreus was in his own mind.

'I have lived through pain, I have died as a child. Having suffered the ultimate sacrifice, I have been denied release. I will defeat Olympus and I will have my revenge.'

Atreus fell into the river styx along with Calliope, Kratos, and Lysandra.

They reach up for air as they entered the realm of Hades.

"We aren't finished Zeus. The gates of Hates have never held me."

A mysterious voice came from behind all of them, "Death cannot hold those with purpose Atreus."

They all look back to see a ghostly figure of Athena, "Athena. How are you-"

"My sacrifice had brought me to a higher existence."

"You still appear to be an Olympian." Kratos says.

"Appearances can be deceiving Kratos."

"So can the children of Olympus."

"But remember that my death came by Atreus's blade."

Atreus clenched his fist, "My blade was meant for Zeus. Just be quick with your words."

"As we speak the war for Olympus rages on and mankind suffers."

"It's only the fall of Zeus that matters. And in case you have forgotten, I nearly killed him if you hadn't interfere. And now here you are wanting Zeus dead. What brought your mind to the right path?"

"I see truths were I didn't before. To destroy the king of the gods, you must seek the source of his strength. The flame of Olympus. Remember as long as Zeus reigns, there is no hope for mankind, all of you must destroy the flame and the foundations of Olympus will crumble."

They continued to move all around Hades as they see Hephaestus locked in a cavern as he cried out, "Leave me be, I tell you I have payed the price."

Calliope spoke out to assure the blacksmith, "Calm yourself Hephaestus, it is only us."

Hephaestus in his giant form turned around and was relieved, "It is you. I thought Zeus would killed you all by now."

Kratos joked, "I thought you would have escaped this cavern by now."

Hephaestus chuckles and gestures to Atreus, "Zeus may have imprisoned me here. But you are the reason that I live in torment."

"I did you no wrong Hephaestus, we just need to take the life only Zeus."

"Well as long as it's only one Olympian."

"We seek the flame of Olympus. Do you know where it is?"

"For what purpose Scandinavian?"

"The purpose that we have chosen, now tell me do you know of the flame."

"All true children of Olympus know of it. We have all come to respect its power but do not be fooled by its glow. Neither god nor man can touch its lethal flame."

Lysandra stepped forward, "We only need to find it."

"Hmph, if you can find your way out of the underworld I'm sure you can find your way to the flame of Olympus."

Atreus sighs as he turned around to walk away with Kratos and Lysandra following in pursuit.

Calliope looked at Hephaestus and replied in a kind manner, "Thank you for your help Hephaestus."

The four warrior's continue their journey as they see a statue of a young girl with a blue fire appearing out of its hands as Pandora appears, "Father? Oh."

Atreus looked at the blue fire, "Do I know you?"

"No but I know who you are."

"You know of me."

"They said that you would come."

The voice of Hades came from all directions, "Playing with toys, Atreus?"

"Reveal yourself Hades, this another one of your tricks?"

"As usual Scandinavian, you are gravely mistaken."

"Face us, Coward."

"So eager Atreus. Relax, soon enough we will have our time to play."

Atreus and the Spartans enter the palace of Hades, they encounter many undead enemies as they crash through the statue of Hades within the palace as they see nothing but darkness. Calliope summoned a light sphere to give some light to see.

"Ah, Atreus, Spartans. So glad that you could stop by. After all we need it. I sense some bad blood between us. Let's see, how many sins have you committed against me, oh that's right you murdered my niece Athena and you kill my brother Poseidon. And do you not forgotten that it was you who butchered my beautiful Queen. I will see you suffer as I have suffered. Your souls are mine." Hades says as he stepped out of the shadows as to catch Atreus's soul first but Atreus uses his strength to being his soul back to his body.

Hades fights the warriors as they continue to avoid his attacks and began to attack him from all directions. He knew that he had no hope winning this fight. Calliope climbed on the back of Hades as she began to stab him multiple times, she front flips forward and lands on her feet as Hades began to swing his blade to hit the ground as it broke apart to reveal the river styx. Hades was on one side as the mortals were on the other. Hades and Atreus both launched their blades forward as they got tangled by the chains, Atreus uses his beast form to pull Hades in, Atreus puts the chain to the roof and pulled it back so Hades's face can hit the roof multiple times, it was honestly a funny sight to see. Atreus pulled in the chains for Hades to fall into the water and gain the claws of Hades. Hades emerges from the water more bigger but Atreus decides to take Hades and his soul, once that was finished for good. Hades was dead the rest of the souls that he stool began to roam the underworld.

Atreus and the Spartans returned to Hephaestus's cavern.

"Can it be. Does this mean, lord Hades rules no longer."

"The god of the underworld is dead." Kratos replies.

"Dead? Ha, Hades deserved to suffer thought I his death impossible."

"Olympians over estimate themselves."

"Interesting. I will keep that in mind Spartan."

Atreus looks at the portal to the right.

"That portal has been used for centuries. I am sure it is broken otherwise I would've seen my beautiful... You know I wasn't always like this. A monster. I was the most prized craftsman in all of the Olympus. Zeus rewarded me with my marriage to the beautiful Aphrodite. At the day you killed Ares was the day my world was torn apart. Zeus became the fiend you now know and worst of all he took my beloved daughter Pandora. I spend my time here trying to recreate her."

Everyone looks at the statues above Hephaestus, "I fail again and again."

Hephaestus then looks to Atreus, "You, you Atreus. You can bring her back to me."

"Pandora isn't really much of my concern Hephaestus." Atreus says as he turned around

"But surely you can understand that, you once had family too." Atreus turned his head when he heard that.

"That part in my life is gone forever. There's no hope of it returning." With they all take their leave as they walk to the portal out of the palace of Hades. They finally walk through as they see the city of Olympia.
