Atmospheric Conversion Center
Atmospheric Conversion Centers (a.k.a. Atmospheric Processors) are large facilities that "suck in air, treat it, then belch it back out".
They are supposed to deal with the steady increase of toxins in the atmosphere of Oni's world (Cf. BioCrisis).
Every major city has its air cleaned by one or several such facilities.
Atmospheric Conversion Center
CHAPTER 07 . A FRIEND IN NEED and CHAPTER 08 . AN INNOCENT LIFE are in fact two parts of one mission. The transition is essentially seamless, however the player's inventory is reset. Same as between CHAPTER 04 . TIGER BY THE TAIL and CHAPTER 05 . HOT PURSUIT
Add descriptions of Konoko's descent, screenshots of the architecture, terminal readings...
Add a description of Konoko's encounter with Shinatama and escape from the compound...
There are a couple of references to atmospheric processing other than at the ACC. Either early hints at Muro's STURMANDERUNG plan, or late revelations thereof.
CHAPTER 01 . TRIAL RUN
Dispose of the combustion engine parts contained in shipment 2Y-224-B, but keep the shipping containers.
There must be no chance that the parts can be tracked back to the original order. Repack the shipment with the Atmospheric Densifiers present in shipment 3X-302-C.
Weights will be added to match the original recorded tonnage, but we aren't expecting anyone to open the crates so they will only need to pass a casual inspection.
CHAPTER 02 . ENGINES OF EVIL
- From the Diary entry
- This place is really big. What the heck are they making here? Weapons? Robotics? They must be building something large. I'd better check the data consoles to see if I can figure out what it is.
- Some of this stuff looks like atmospheric processing equipment. I can't believe I KNOW that! Maybe that means I'm a nerd?
"I'd better check the data consoles to see if I can figure out what it is." - a typical gameplay hint, which actually leads to information on the Deadly Brain. Thus the puzzling "engines of evil" are apparently unrelated to the atmospheric processing equipment, which Konoko identified by herself (in the original Oni, it is not clear what part of the facility she is referring to in either case).
CHAPTER 05 . HOT PURSUIT
Unexplained interference in Sector N31 has been reported to create "ghost" signals which may be displaced echoes of standard guidance transmissions.
Report all incidents of ghosting to NavCom Central. It is believed that a malfunctioning Atmospheric Processor may be responsible for the rogue emissions.
A Crisis Control response team has been dispatched and will file a follow-up report in 28 to 32 hours.
CHAPTER 14 . DAWN OF THE CHRYSALIS
Rather ambiguous and untidy references here, mostly valuable for the number of ACCs and control stations worldwide (Tertiary Stage). 417 ACCs means the population is mostly concentrated in today's million-plus cities.

Distance to cities
It is not clear how close the ACCs could be to a city's center/suburbs. It doesn't make sense to place an ACC too far away and in a Wilderness Preserve (too much decontaminating work). But if they're too close, you end up with toxic waste (the product of decontamination) right next to a city. Unused dialogue indicates that the ACC was conceived of as being underground, which would explain a few things, including the fact that most of the clean air seems to be pumped through massive "lines" such as the one seen at the end of CHAPTER 08 . AN INNOCENT LIFE instead of simply released into the open air. Those lines must run up through the city's foundations, which would explain how they're able to get close to a city without dumping waste in the middle of it. Note that ambient street sounds (police sirens, car horns) can be overheard in CHAPTER 07 . A FRIEND IN NEED even though no city is visible, adding further evidence that the city being served by the ACC is much closer than you'd think from your surroundings.
