Fun fact: Here's the raw loading screens for each area in the game.
And here are some special loading screens that aren't normally used:
Fun fact: In version 1.0.1, male Akira was made 5.5 kg heavier, and Female Akira was made 3.5 kg heavier. (According to IRIS data.)
This meant Akira went from:
58.3 kg (128.5 lbs) to 63.8 kg (140.7 lbs) [Male Akira]
45.8 kg (101.1 lbs) to 49.2 kg (108.5 lbs) [Female Akira]
Considering they're both 19 years old, and Male Akira is 171.4 cm (5'7") and Female Akira is 169.3 cm (5'6"), they probably did this because the 1.0.0 numbers would make female Akira underweight, and male Akira almost underweight. The weight increase pushes them right to the center of healthy levels.
Since, I assume fighting chimeras all day would help you keep at a healthy weight!
Fun fact: This graph shows the number of Astral Chain NPCs that are born in each year, based on every IRIS data entry in the game. (The game takes place in 2078.)
The small blips are Yoseph (2015), Jena (2023), Max (2030), and Lappy (2076). Otherwise, it follows a stepped distribution, with a large gap between 2058 and 2066.
The disturbing gap may be because the developers didn't want to make teenager NPC models... but maybe it was caused by chimeras?? Or UNION-enacted birth control??
Fun fact: In v1.0.0 of the game, it was possible to get Lappy to tell you "You got a perfect score!" when you actually only scored 75/100 points, due to a error in the talk script logic.
This was fixed in v1.0.1.
Fun fact: In version 1.0.0 of the game, Parnassus No. 2 actually had an ID on the IRIS! It was UCA002684.
This ID was unique and not shared by any other NPC. He was the only Parnassus to have an ID, and it was later redacted in 1.0.1. If you go check him in File 02 now, it'll just say ID: ?????????.
Fun fact: Kijima is the only person in the game to have had their birthday retconned between updates. In 1.0.1, the developers changed his birthday from June 27, 2050 to February 3, 2050 (144 days earlier). They also added his blood type and bust/weight/hip ("size") measurements that they somehow forgot to add in 1.0.0.
Fun fact: In the localization notes included in the game's files, Hal's "Strange Drone" form is labelled as "謎のドローン/H9-T0".
And if we look on his backside, we can see a few of his stickers saying H9-T0! That's probably what he calls his drone.
Also, here's what Hal looks like without his stickers:
Fun fact: This is what Hal's "t-pose" looks like.
