The 1.5 patch that came to Cyberpunk 2077 in February of this year actually contains extremely important information for the first DLC of the game. In the first version of the patch, CDPR probably accidentally added all the dialogues of the DLC to the files, but these dialogs were not leaked for a long time.
Now, the leaker of these dialogues says that this is a legal leak and that anyone who wants to can download the first version of the patch published on February 15 and open the archives of the lang_text and see these dialogues.
The files were not complete, most side tasks were not used instead of temporary texts, but it can be seen that there will be seven main tasks in the expansion pack.
The expansion pack will take players to the Combat Zone (Pacifica region), which is available in the main game but not accessible. Although this area was not accessible in the main game, it was included in The World of Cyberpunk 2077 drawing book.
The person who gives us a task in the DLC is Netrunner named Songbird. Songbird enters V’s head and replaces Johnny Silverhand. In fact, it would have been expensive for Keanu Reeves to re-enter the role for the DLC, to take his time, to do voice-overs, etc. So CDPR saw fit to make such a change.
It seems that some changes have been made to this DLC at the end of the game, these are small things, but there is still no need to spoil it.
