After Fraul Engel was killed by the hands of Blazkowicz, the people are started to revolution against the Nazis across the USA. Thanks to Blazkowicz, Grace became a captain of the new Auzmerzer known as USS Battle Glory, aiding the resistances as they able to liberate their hometowns. They liberate California, Nevada & Arizona every day, they were successful and establish in each base. Blazkowicz and Anya got marry as his wishes come true just like his mother said before she died. A few days later, Sigrun & Set went to him to go to annexed Great Britain to stop the secret project at the facility that Set can hack the systems to find out their plans. Then, he went off to Great Britain as he's ready for the battle by stopping the Nazis from making a dangerous project.

...

BJ Blazkowicz was in the Nazi facility to destroy anything that Nazis are used to against him and everyone else. He ran through each room to clear out the Nazi soldiers in the hallway. He then grabbed a Nazi soldier's throat to the air and throw him at the wall hard. Another Nazi soldier was about to shoot him but he got shot first. 3 Nazi soldiers came and shoot him as he dodges the bullets and take cover behind a wall. He returned fire as he manages to kill three of them and went on. As more of Nazi soldiers come to kill them, he shoots them all with his AR-60 gun as he continues running towards it. He then calls his team and said on his earpiece.

Blazkowicz: Alright, I'm here. So, what do you got info about this?

Sigrun (radio): What I know about their secret is they building something that leads to another world known as 'Das Tor'. In English, The Gateway.

Blazkowicz: Oh great! They building a gateway so they can invade more worlds. I got to stop them.

Sigrun (radio): Yes. You must stop them. Now, you have to go to the left hallway, then go to the right side and then, you can see a whole room in which it is where the gateway was built.

Blazkowicz: Okay then. Just be sure Anya is safe there, okay?

Sigrun (radio): I will. Good luck.

She said as she ended the comms. He went to the left hallway as Sigrun said. He encounters 4 nazi soldiers holding their AR-60 gun & Maschinenpistole and they fired at him. He takes cover at a small crate and return fire at them. He killed at least 2 of them and he goes to a nazi soldier as he grabbed his throat and throw him at another nazi soldier as they both laying on the ground and he fired at them, killing them. After that, he went to the right side and open a door to see a whole room and he sees a lot of equipment & materials and also, he sees a gateway which he was surprised to see it and also, it is a prototype.

He's focus at the gateway when he heard a voice coming from the ground floor. He moves slowly in stealth to hear of what they were talking about. As he avoided getting caught from Nazi soldiers, he hid behind the crate and see 2 scientists having a conversation.

Nazi scientist 1 (German):  So, what do you think about the other world? Is it amazing to see more people in the other world?

Nazi scientist 2 (German):  Yes. Imagine, we will take over your world and it will belong to the Third Reich. We will be rich if they succeed it!

Nazi scientist 1: Hahahahaha! Ich mag es, dass du das sagst. Standartenfuhrer Hanz Jossëphfurër wird diese Armee zum Ruhm führen, und der Führer wird stolz sein.
( Hahahahaha! I like that you say that. Standartenführer Hans Jossëphfurër will lead this army to glory, and the leader will be proud.)

As they said, he feels like they're planning to invade other worlds. It would be the next Nazi empire in other worlds of that happens. He also mentions that "Oberst Hanz Jossëphfurër in charge of the operation so he decided to put the end of the operation as he stand up and said to them.

Blazkowicz: Hey! You Nazi fuckers!

He said as they both looking him surprised & shocked to see him.

Blazkowicz: You ain't going to invade another worlds! I will destroy that machine of yours!

Nazi scientist 1(German) : Oh no! It's him!

Nazi scientist 2 (German) : Alarm schlagen und den Amerikaner töten! ( Sound the alarm and kill the American!)

He said as they both raising their pistole at him but they both got shot first before they pulled a trigger. Then, an alarm sound as more Nazi soldiers came to kill him. He takes cover as they open fire at him. He used a Kampfpistole to fire at them as they got exploded into the pieces. Then, a gate was open to see 6 elite soldiers and 2 robot guards came in and started shooting at him. He switched a kampfpistole to double AR-60 gun as he shoots at elite soldiers first. He killed 4 elite soldiers while the others take a cover and fired at him. The robot guards fired their heavy laser cannons at him as he went to take cover. He throws electric grenades at 2 robot guards as they are electrified and unable to move. He went behind their backs as he fired at both weak spots and then, he gets away from them as they started to explode. 2 elite soldiers came out from hiding and fired at him but they got both shots by his MG60. Once he's done killing them, he went to the terminal to find a self-destruct button to destroy it.

Blazkowicz: Where is it? Where is it?

He keep looking at it until he sees a red button with a word "Selbstzerstörungstaste".

Blazkowicz: What is this? Selbstzerstör- wait a minute, it means self-destruct button. Okay, here it goes.

As he said, he was about to press a button when suddenly, he feels someone is behind him. But it's too late as a figure hit at his head with his baton. He fell on the floor as he sees a figure in blurry vision and then, he said to him.

???: What do you think you're doing, american?

That what he said before his eyes went closed. In a few minutes later, he opened his eyes to see himself being tied up with chains. He tried to struggle to escape but it's no used. He also noticed his earpiece is gone. He looked up to see a nazi wearing a dark SS uniform with a black coat on it and 2 of his elite soldiers holding their MG60 gun as they aiming at him. He saw a bag filled with his weapons beside an elite soldier. He gives a glared at him & said.

Blazkowicz: So, you must be Standartenfuhrer Hanz Jossëphfurër they talking about.

Hanz: Ahh... It seems like you know me. Well, no need for introduction then. Such a shame.

Blazkowicz: I know you're planning to invade at other world with that gateway!

Hanz: That's right! We are going to invade another world. Our Fuhrer wanted it more so we can become the finest Third Reich in the universe.

Blazkowicz: You already conquer the entire world here! Why there!

Hanz: Well, I have two answers from you; One, We got desperate to win. Two, We need more land to conquer. Is it amazing to become a conqueror for the Third Reich, my American friend?

Blazkowicz: You just be another Nazi asshole.

He said. Hanz swings his fist at his face so hard. He finally decides to kill him as he pulls out his Luger P-08 pistol and aim at him.

Hanz: Ahh... It's been fun to see you in person. But I'm afraid it's time to remove you from this existence. So, any last words?

Blazkowicz: Yeah, you should check behind first.

Hanz: Huh?

As he said, they heard footsteps coming their way. It getting closer, it reveals itself a green painted panzerhund enter a facility.

Hanz: What the!?

Blazkowicz: Hey, Samantha. There's your treat. Sick 'em.

He said as it obeyed his command and it went straight to Hanz.

Elite soldier (German): Heer  Standartenfuhrer! Watch out!

He pushed his colonel as panzerhund (aka Samantha) bite an elite soldier and kills him. Hanz said to his elite soldier.

Hanz (German) : Fire that panzerhund!

An elite soldier tries to shoot it, but Samantha breath fire at him, scream in pain as the fire consumes him. Hanz was shocked to see a panzerhund was reprogramming by an American. He look at the terminal that gives him an idea. He pressed a button as the gateway is turning on and started to suck in it. Blazkowicz breaks free the chain but it's too late as the portal started to sucked him in. Not only that, his reprogramming panzerhund is sucking into the portal as well. He holds tight on the floor to try not to let go. He looks at Hanz as he said to him with his angry tone.

Blazkowicz: Hanz! If I see you again in the another world, I will kill you! You hear me, I'll fucking kill you!

Hanz: I hope we'll see each other again in other world. Auf Wiedersehen, mein amerikanischer Freund! ( Goodbye, my American friend!)

That's his last words he ever heard as he lost his grip and sucked into the portal. After that, he closed a gateway and started to laugh as he success to remove the greatest threat of the Reich. Then, he said.

Hanz (German): Now let's assemble my army and start the invasion.

...

As Blazkowicz traveling through a portal, he feels started to feel sick as he wanted to vomit out from his mouth. A portal appeared out of nowhere in the forest as Blazkowicz and Samantha are landed on the ground. The portal disappeared and they are now stranded in the strange world. He groaned as he manages to stand on his feet. He looks around the area to see the trees everywhere around him.

Blazkowicz: Where the hell am I?
