As I understand it. And I understood it roughly. The game will be released in chapters, possibly. I repeat, this is POSSIBLE, but there is information in the discord group that it will be like Ultrakill by chapters. And I didn't understand what this was about. Therefore, I think it will be released in chapters and they can easily manage to release one chapter by the end of this year and deal with the next one.
P.S. These are just my guesses and I don't need to keep them as the truth, maybe I'm wrong. I'm probably even wrong.
