First off, I want to say like most people, when they announced YoRHa: Dark Apocalypse from FanFest a few years back I collectively lost my mind.
"We're getting NieR Gear!"
Disclaimer: I am a Yoko Taro fan. I've enjoyed the series since the first Drakengard game. So seeing a crossover of this magnitude was pretty amazing and overwhelming in a good way.
From the beginning...
5.1 - the day The Copied Factory dropped. We're introduced to 2P who, a lot of people argued that it was the 2P from Soul Calibur (it wasn't). What we knew was that, like YoRHa from Automata, the machine lifeforms were the enemy. My first thoughts from entering the Copied Factory was "Huh... this place is falling apart. How long have the machines been on Norvrandt?
Alien Manifestation begins to play.
This rush of adrenaline came over me of an "Oh shit! Here we go!" moment of goosebumps taking me back to when I played Automata. I was experiencing sensory overload and still asking why or how this structure is here.
Well into the dungeon we get to the tank and the flight unit fight and all I could think of is "Oh man! Imagine if we can get a flight unit as a mount!" while trying to dodge a giant AOE. Getting to Engels and taking him down was awesome. Funnier more so when people tried to jump to the platform only to clip thru the railing prior to Engel's coming to a complete stop against the platform.
I laughed. A lot. Because it also happened to me.
Once we got to the final boss, 9S, I thought "Wait a second, what is going on and why are we fighting him?"
After the fight, the cutscenes and needing to find this "key" that 2P mentioned, it had me asking more questions such as "What version of 9S is this?"
Post story we are able to explore The Copied Factory and pick up reports of note which give us some kind of backstory(?) and more vagueness. When picking these up I wondered if these are pieces to a bigger puzzle down the road. (Spoilers - they weren't. More vagueness)
For several months a lot of theory-crafting happened between a lot of NieR and XIV enthusiasts. 5.3 rolls in and a new quest pops up.
"Everything you know is wrong"
And boy, it wasn't kidding. The crashing of the Bunker on Duergar mountain, the attack on the dwarven village, 2P's betrayal and 2B making an entrance, we're suddenly greeted with another dungeon - The Puppets' Bunker. We're greeted with new bosses, white YoRHa combat units, enhanced Flight Units, the ruins of the bunker and an odd new entrance from the Command Center which leads to the Alien spaceship.
"Huh.. okay.."
Like many, it left us with a lot of questions. For me, I asked if this was another Alien ship (If you recall from Automata, we did discover a ship buried deep underground) and what of this particular Bunker? Is it a copy or is it the original which somehow got swept up somehow. We talk about the how's a bit later.
Post dungeon you are left asking more questions than not.
Revisiting NieR Automata when you are in control of 9S after the giant fight with Eve, I take note that 2B's dialogue after the dungeon leads me to believe that she might be a version of 2B prior to when 9S cut off the data transmission after discovering some kind of glitch within The Bunker's database - most likely before the backdoor opening up for the Machine lifeforms to inhabit the Bunker's systems and infecting all of YoRHa who were still connected to its systems prior to its demise.
It's my opinion that this 2B and 9S were that prior to 9S pausing the upload before the fall of YoRHa.
Back to FFXIV....
We are given another exploration/fetch quest for the logs inside The Bunker. We learn about YoRHa's function, find some data here and there, have the ability to check out 2B's room and just relive some nostalgia while listening to familiar NieR music.
The dwarves begin to blame Anogg and Konogg for the events leading up to the destruction of their village, 2B comes to their aid against the angry mob and Anogg then disappears as if to have a "crisis of personal faith" or something like that leaving Konogg to deal with the village's vitriol and him solely trying to make things right - only to have him retreat away in the caves again, pining for Anogg to come back.
The side quest also glimpses into the twins past, including encountering a familiar white orb while trying to find Konogg after he's greeted with more vitriol. We're lead back into the Bunker and to the Alien ship which we're treated with a scene when the echo shows us a glimpse of Anogg and Konogg's past, what eventually happens to Anogg and Konogg encountering a white orb, which spawns what looks like a copy of Anogg.
Once again, more and more questions.
We then get to patch 5.5 - The Tower at Paradigm's breach.
We find Konogg at the white orb at the alien ship again with the white orb (which we all now know is a Seed of destruction/resurrection - see Drakengard references there) and an unconscious Konogg followed by a wave of 2P's emerging from it.
By the way, did anyone get Femmebot vibes sans Austin Powers when we saw all of those 2Ps just appear? Just me? Okay.
We are then joined by Anogg, 2B and 9S - the femmebot 2Ps do a thing and suddenly we see a giant white tower popping out into the sky looming past The Bunker. After some dialogue I now firmly believe that the version of 2B and 9S are the ones prior to the paused upload as I mentioned above from the events of Automata. Going thru the Tower fights themselves I felt confident of that conclusion.
We are greeting with hacking and the network - odd how non-androids like us can access the network of machines, but I won't question it. It was pretty cool! The first fight we are greeting by a familiar Gestalt. Further in we encounter a second fight and more bosses from another NieR series not of Automata, but of the stories before it.
The elevator mini bosses were annoying and actually fairly challenging - but have different names from the ones from Automata themselves (and greater pushovers).
But that final boss.... you just know at this point was a marriage between Drakengard and NieR games across. I never thought my character would be on the rooftop overlooking all of Tokyo/Shinjuku and dodging incoming trains and what I believe is the Square Enix building during mechanics. (I've visited that building several occasions in Shinjuku and it looks very much like that so.. XD )
We've reached the end of the fight - Anogg comes to grips that she is not a dwarf, passes a letter to give to Konogg (to which we never know what was written..) and then uploads herself into the data stream while 2B and 9S are trying to close the rift between worlds. If you played Drakengard you'll recall how the Seeds of Destruction work along with a certain final battle and an alternate version of Earth.
As the dust settles, we see a lifeless 2B and 9S laying together in the same fashion of Automata's ending and a Pod playing back a final audio log from 2B, what seems like is directed to the player directly.
The Tower then becomes unstable and you retreat back to the town. Arriving you have more dialogue with the dwarves and more banter between them. Beyond that, Konogg decides to leave and learn all he can about the objects leading up to YoRHa and the Orbs.
For the next five weeks we are greeted with a weekly quest that some of the dwarves ask us to do mainly to get the town back to where it was before YoRHa trashed it. Each week we see Glagg going into bouts of Extreme emotional Bipolar behavior (reminisce to the red eye virus from Drakengard)
The final week of the quest the chief tells us Glagg was found at the end of the alien spaceship, face down but then is revived like nothing happened and all is well.
Five point Five-Five drops.
The chief asks us to look for Konogg which takes us to Eulmore. We speak with a merchant who says that Konogg made an order with him and asks us to deliver it to him - in the shanty town below Eulmore.
We're greeted with another cutscene of Konogg trying to figure out how to utilize the orbs to bring his sister back. After several emotional and brief scenes, we see a helmet-less Anogg taking Konogg's hand, exclaiming that there's an "entire world to explore" and they walk out, hand in hand, into the light...
I guess... take that scene as you will... it was vague, short but really emotional.
You arrive in Konogg's shack and he is nowhere to be found aside from his own hat which he left behind. You return to the village and speak with the chief which you're given an option of how to handle the item Konogg did not claim. The chief says at the moment there's nothing else to be done.
And that's it...
