Wynne might have been human once. It's hard to say.

Now he's a bunker core, a nanomachine controller responsible for an entire complex.

Of course, the place is a bit wrecked. And the world outside is ruins. And he's pretty sure that whoever put him here is going to come looking for him at some point...

Dungeon Core, Post-apocalyptic style. Come for the mutants, stay for the dystopian adventure!

High-tech Dungeon Core

Reviewed at: Part 2-1

I originally found this story on Amazon, and it didn't occur to me until just now that, considering this is the same author that wrote Threadbare, Bunker Core might also be found here. This review will primarily cover the first book, as the sequel was only recently started.


First and foremost, this is essentially a sci-fi dungeon core story that is set in a post-apocalyptic world where humans scrabble to survive and oldtech refuses to give up and die. The setting is well designed, with a wide world built out but cleverly limited to the perspective of the protagonist that finds himself inside of a futuristic core with only snippets of memory to guide him. This is a precarious balance to strike, as it seems common for authors to aggressively dump information in ways that don't always make sense, but Andrew Seiple does an excellent job revealing the world and the varied forces each with their own agenda piece by piece as events occur around the MC that is just attempting to survive. The limited perspective does make some portions confusing, but always in the sense that neither we nor the MC has enough information to really understand what's going on, rather than things being poorly explained. It breeds an appreciable sense of paranoia in the protagonist and leaves the reader simultaneously interested an apprehensive whenever new factions reach out.


The litrpg elements are fairly light and seem realistic, though the explanation isn't exhaustively described. The limits on the dungeon core growth and function are holdovers from the original growing design of the AI core. Allowing it to slowly build up complexity and specialize in function as it adapts to the requirements of the facility it was installed in. The various programming blocks and the workarounds designed to circumvent them made for an enjoyable progression. Additionally, there is no requirement that the core kills things to grow, making for an underlying drive that, for once, isn't fundamentally bloodthirsty. The characters are interesting and overall make reasonable decisions based on their circumstances and the few chapters from other perspectives serve to provide an interesting backdrop to the central plot progression, even when they never intersect with one another. The writing itself is flawless as well, which makes for a very smooth read.


The only complaint that I have is that the base building was hampered by the core struggling for survival from the very beginning, as much more powerful factions attempt to ensnare him in their agenda whenever they discover him. There is a great deal going on in the ruins of the world, and as much as I enjoy the sense of the MC scrambling to scrape out from under oppressive forces, I also want him to use the power and tech he possesses to build a proper base and help the few friendly remnants of humanity reclaim the world. Personal hopes aside, I'm greatly excited that the author has started on the sequel and I can't wait to see how things develop going forward.


If you like the Laboratory

Got hooked in on it. This is a dungeon core story mixed with fallout. The novel is still in the early stages but so far I like what I am reading.


A fun engaging story with great characterization and flawless grammar and spelling, much like the author's previous works.

Let's hope this story doesn't sell you on a fun and engaging premise before devoloving into an increasingly depressing downward spiral of betrayals, horrific acts, and tragic characters without anywhere near enough triumph and cuteness to justify the emotional trauma it inflicts on its readers...

Soapbox: I'm still gun-shy from how much Threadbare jerked me around after selling me on such a cute uplifting premise. I have no problem with Grimdark novels per se but the misery needs to justify itself with gleeful amorality a la Everybody Loves Large Chests or with rewarding insights and concepts.

If you're deconstructing morality and subverting the hero's journey there needs to be some pay off. The more invested I was in Threadbare's world and characters the more the story hurt me and it only ever got worse. Here's hoping this time's different.


It's very well written, from start to finish, the pacing, characters, plot, world building, everything is perfect. I liked the interludes and hints of the much bigger odds and stakes at the very beginning and the backstory of side characters, and the lack of exposition dumps. It's obvious you put a thought into it and it shows its briliance. How common fantasy elements are transformed to a sci-fi setting and tie together the essense of what dungeon should be is genius, even the pixie... The whole story flows smoothly and I binge read it all in one night and didn't get enough.

I hope you return to it. I liked this more than Threadbare honestly and will read your new stories too, but I wish for a continuation of Bunkercore above all else. Also please make a patreon :)


A great new spin to the usual Dungeon story.

Review as of Chp 25

An excellent story with great characterization and a very engaging plot.

The fact that it takes place in a Fallout style future instead of the usual fantasy setting is a great addition to the story and the plot develops far past the 'grow-dungeon' that seems to be all some other Dungeon Core stories ever show.

Truly an excellent new adition to the normal Dungeon Core story.


I don't want to give anything away but it did several things different from the regular dungeon core books, and it did them well.
It still has the power creep thing reminiscent of video games, and the why makes more sense than normal but its still somewhat nonsensical. Him getting more circuits as time passes for some reason. But I like it better than the whole level thing that is prevalent in the genre.
The villain was written in a way that made me concerned that it was bordering on intellectual property theft, and they grated on your nerves. I almost put the book down during one of there monologues, but I didn't and I'm glad I didn't. it makes sense later, just bear with it.
That is really the only negative comment I have about the book, good story, good editing, sensible progression.


Review for Part 2 - Nomadcore

Reviewed at: Interlude: Survivor 4

Review for Part II:

Bunkercore #2 - Nomadcore sees Wynne relocate to a new "dungeon". Largely lost are the crunchier elements like circuit allocation, upgrades, and feedstock. Both the world and the cast of characters expand and existing characters get more depth. The departure from the first book, both in style and in plot, is very different from the first book. Ultimately I was disappointed that my favorite elements were sidelined.


tl;dr its professional level writing, read it and see for yourself

the story is intriguing and the plot engaging, the characters lifelike and interesting, the grammar fucking impeccable, really theres nothing to hate about this story. A nice break from the constant stream of garbage that stems from this site, and most others as well im guessing. well worth a read, theres only a few chapters out at the moment so just try it out, you have nothing to lose and a great story waiting to be read if you continue.


side note, teitoku's review is bullshit. normally i wouldnt mention other reviews specifically, but since there are so few reviews written i dont want some preteen dumbass to hurt the views this story is getting. first of all, i have no clue at all what was supposed to be confusing after chapter ten, literally nothing stood out as confusing in the slightest. its fairly easy to follow whats happening in that section of the story, so im left wondering what the fuck he was complaining about. second, for those of you who dont know, reading someone's mind is a whole lot different from sifting through their memories to find shit out, not to mention wynne doesnt even have any memories for argus to read. one involves passively collecting information distributed across whatever channels exist between the two, and the other is an active attack similar to hacking which the thing clearly couldnt do anyways. of course argus doesnt understand the humour, he literally never encountered it before. last of all, if not having those stupid blue tables is enough to lower a star rating on a story for any large amount of people, then theres literally no hope for this website. stupid shit like that doesnt affect the story, it doesnt even affect the worldbuilding. i dont want to be mean, but at the same time im incredibly annoyed with the standards of certain people on this website. literal garbage gets 5 star reviews here, but this story somehow gets those bullshit low ratings.


note to author: i hope you end up publishing this at some point, im short on money now but id love to purchase a copy whenever its available

Absolutely Fine

Great Story Slow Release Rate

It’s a really good story. I’m writing this as of chapter 24. Very enjoyable, well thought out. It’s of course from the same profile that brought us Threadbare and as such I had high expectations. 

It’s a really good read, very different to threadbare as well. It is of course still in the early stages. 

What’s good about it:

Well thought out. Complex plot. Realistic characters. Not an overpowered MC. An interesting twist on a dungeon core story.

What’s bad:

The very occasional grammatical error. Lack of a schedule. Length of time between posts.

i understand the difficulties of writing. Tried/Trying to write something of my own and it was VERY difficult. But I think it would really help the story if it was:

A: Finished. As in only released when finished.

B: Released on a set schedule so people know not to keep checking back every day after a week (yes, that IS an indicator of how good the story is).

If we get a schedule or the release rate picks up I would definitely rate this 5 stars and change my review, everything else about it is literally great. I would...AM recommending this story to anyone who sees this review. It’s a great story, and that’s so rare on this site.


Excellent, some suggestions

Overall really enjoy the pacing. I am reminded of "the laboratory a futuristic dungeon core" but that's a good thing cause that book is great too.


 You've done a great job implementing the dungeon pixie in a doesn't appear out of nowhere way. Also of implementing the "knows nothing, born fullly aware and ignorant" aspect again in a way that's unique and makes sense.

Some things I'd suggest.


1. Litrpg done well often takes the arbitrary rules of video games that often only exist for balance and drama and such and internalizes them and makes them make sense in the world the book exists in. You kind of did this for example addressing the lock my core away bit with the coding about always having maint access. However I think it'd be good if later the currently arbitary rules about building and sizes of such etc could be explained away as not simply something put in for zero reason. Some things like needing processing power to control things makes sense, but things like you can claim 15 feet for free but 16 feet costs. This should be explained, since you said 15. 2 to the power 4 is 16 and computers count in base 2 and with exponential growth things can get very big very fast, saying each bandwidth is like 16 bytes of data and each square foot is 1 byte worth for some reason etc. You can make this make more sense.

2. I think you should have picked corruption from something other than fumes. Let one of them actually physically damage him a bit and corrupt him that way or let him get a virus/infected and fight it off by the mutant stuff or even by his ally who initially rebels against him rebelling. I found the hard drives of super computers damaged by brief exposure to smoke from old toxins and unrecoverable or at least easily a bit wtf. Like they can basically pull materials from the air but cant' just run his little bots over his hard drive, which seems odd that it'd be damaged to begin with.
