Files containing dialogue and story were datamined.

CD Projekt Red made a little oopsie. According to dataminers, "every line and dialogue" included in the upcoming first expansion for Cyberpunk 2077 were included in some of the game files in a recent update to the base game.

These dataminers have extracted all of the lines of dialogue and all story beats and shoved them into a compressed file, which has been made available to download. The contents of this leak were posted online and are making the rounds on social media and Reddit.

The files contain dialogue lines along with details about the expansion's ending and new play areas. If you don't want any spoilers, then I suggest trying to avoid downloading the file and also avoid reading comments for anything Cyberpunk 2077 related.

A release date for this first expansion still hasn't been announced yet by CD Projekt Red. The studio was more than a little preoccupied fixing bugs in the base game, which pushed the expansion's release date further and further back. Cyberpunk 2077 was released at the tail end of 2020 and has received several updates since to address a myriad of bugs and performance issues.
