With vents after vents being sealed, they've been repelling the Yanderes, combined with the Sentry Guns and Mines. As more of them fall by the guns of the Fireteam...

HN: How many left!?

HCM (Nick): *Finished* Three more rooms and a few more vents to seal!

Justin: ARGH! *Shield Bash!* More of them are coming! Sentry Guns and ours aren't going to last without ammo!

HCM (Nick): Pull back then! I'll deal with the rest!

While Nick went to seal the remaining vents and tossing mines into the vents for additional time. The rest, Minato, Justin, and Hà Nội is in deep trouble. Because they're dealing with the Eagle Union and Ironblood Shipgirls.

HN: Both Americans and Fascists!? What a god damn nightmare!!!

Minato: You don't say?

Justin: We're getting pushed back here, Nick! Hurry with the vents!

As they continued to hold the ground, Nick kept the yanderes at bay, using the M39 SMG to take down one by one of the crawling Yanderes. This time, after the final vent, is reinforced. They quickly went to the shockers, Justin kept the sleeping darts from hitting him and his teammates, with his shield. Until Bismarck with her cannons...

Justin: Uh oh...

HN & HCM (Nick): JUSTIN!!!

With the barrage, Justin's shield is destroyed sending him back to the wall. Knocking him out, with the electricity restored, they pulled back to the next elevator, with a knocked down Justin pulled into the elevator.

HCM (Nick): The Blast door!

HN: Then hold the line! Once it's closed, we're safe!

More came out, and they fired at will, Planes, Shells, and charging Yandere Shipgirls.  The Duo held the line as the Blast Door in front of them are closing. The sounds of the M41A3 and M41A2, by Nick and HN, has been stopping the yanderes on the track with Napalm Grenade and Grenades. With Minato's...

HCM (Nick): Now, Minato!

Minato: Persona! Megidola!

Another horde taken out with a blink of an eye, Minato is now exhausted... Only for this...

Enterprise: AHAHAHAHA!!! FOUND YOU!!!

HN: What the!? Enty!? 

HCM (Nick): She's a lost cause, cousin! Just keep firing!!!

Enterprise: You're mine!

Minato headshot Enterprise with his pistol, finishing her off. With the Blast door about to close...

Minato: Wait... Why it's getting hot in here?

HCM & HN: Belfast's Chems!!!

It's the chemicals, they quickly sealed the vents and push the blast door to close it quickly, their gasmask won't work due to the chemicals mask piercing. With it closed, and they rushed to the elevator. As the elevator goes down to the third base...

HCM (Nick): Ok... That just went from bad to worse... Now, we got the Eagle Union...

HN: And!? We now have to deal with the Eagle Union! I can't believe Enterprise went crazy...

Minato: Huh. No wonder.

Minato just pokes the unconscious Justin with his sword. While Nick and Hà Nội...

HCM (Nick): Looks like we're not going to last...

HN: Looks like it. We can still kill them, but... I doubt we'll last with empty magazines... Or even with our swords...

Nick took out his Crusader Sword while Hà Nội with his Optimus Prime Sword.

HCM (Nick): *Sighs* Our duty is not over... We must complete our duty, for God, for Saint Andrew, and for the Human Race...

HN: You and me both, cousin...

Justin: Ugh... My head... What happened...?

Minato: Blown by Bismarck.

Justin: Can you stop poking me with that sword!?

Minato: Ok...

HCM (Nick): So... Does anyone wants to work in SpaceX? I heard Elon Musk is building a Colony on Mars.

HN: No, if we could at least cure Enterprise.

Minato: Not interested.

Justin: Sure. As long, Alice doesn't come.

HCM (Nick): Well, at least we'll be buying time for the others to escape...
