Since I haven't delved deep into the 'white noise 2 game story', I can only speculate. There could be a character who is a skeptic at first but is gradually drawn into the mystery of the white noise. Maybe there's also a character who has some sort of psychic ability or is more attuned to the supernatural, which helps in uncovering the secrets of the game's setting. It's also possible that there are multiple characters with different backgrounds and motives, all brought together by the allure of the white noise and the mystery it holds.
The main characters in the 'white noise 2 game story' might be ordinary people who find themselves in extraordinary and spooky situations. They could be researchers who are intrigued by the phenomenon of white noise and decide to explore the source. Or perhaps they are just regular folks who stumble upon a place filled with the mystery of white noise and have to figure out what's going on. Without playing the game thoroughly, it's hard to say exactly who the main characters are.
I'm not certain about the specific main characters. It could be a group of investigators or just a lone adventurer.
