This story is not survival horror, sure, it might be up to chapter 50 or something but from there, the whole thing just becomes "let's make shit up as we go". They established nothing from before, and shit just starts popping up from nowhere, this is introduced, that is introduced, basically, the setting is minimalistic, the twist is that, ha, there is even more settings you knew nothing about! Okay. So instead of working what we got, we get mountains of expositions on what everything is. That's what make the story so terrible, other than the abrupt tonal shift.

I want to say I am pissed that they literally made up a bunch of shit that has no establish connection to what was already presented, but honestly it's kind of hilarious how it went from [POTIENTIAL SPOILERS] minimalistic steampunk survival horror to full-on modern world borderline Gundam storyline about spies and war with a segregated race that can pilot the Gundam with a lot of other shit introduced to fix up plotholes regarding why they aren't fighting back despite being oppressed and presented with powers. [POTIENTIAL SPOILERS END]

The characters are also so dull when one character was said to have died, I went "meh" meanly because they were given no real personality and was inadequately developed. I really don't care about them after they changed the theme from "struggle for freedom for humanity" to a goddamn war story with even more shit being made up along the way. I heard AOT's original story got leaked or something because I can really see why. Shame, the first half was mysterious and good.
