During Summer Game Fest, Techland released a 30-minute gameplay walkthrough for Dying Light: The Beast, its upcoming zombie RPG. At around the 29-minute mark, protagonist Kyle Crane radios a mysterious character called Olivia, informing her of his successful mission to kill one of the antagonist's monstrosities. According to Samantha Béart, the actor behind Karlach in Baldur's Gate 3, Olivia's voice is their own, yet Béart tells PCGamesN they were never actually cast.
