I at first considered listing all the dialogue modifiers in the game here, or even the dialogues themselves, but it would be as tedious to read through as it would be to process the text for this guide. A lot of text also changes between different versions of the game.
So, here's an easier solution: you can download a dump of the parts of game code containing all the chats, logbooks, cutscene chats, scrambler modifications, and other details. It's difficult to read, especially when it comes to modifiers, but it's better than nothing - the documents I used to write the script before inserting it into the game are all outdated.
