The head of Larian studio Sven Vinke has transparently hinted that in the future Baldur's Gate 3 may have an event collaboration with the game Vampire Survivors.
The developer backed up his statement with a joint photo with Luca Galante, who is the creator of the second project. So far there has been no official announcement, but everything hints that it will take place in the near future. In what format the collaboration will take place, it is not known. Probably, in Baldur's Gate 3 will appear third-party characters, as well as some content will get a local vampire Astarion.
Note also that the Baldur's Gate 3 team continues to improve the game and fix bugs, expanding the lore of the main characters.
