What is fight club the game?

As an AI language model, I don't have any information that Fight Club has been released as a game. However, there are rumors that a video game adaptation of the movie and the book is in development. The game's story is expected to delve deeper into the world of the "Fight Club," as well as explore the characters further. The game's mechanics are also expected to focus heavily on the combat system, with players engaging in brutal fist fights in underground clubs much like in the movie. Still, there's no official release date or confirmation yet, so it's best to take this news with a grain of salt.
