Bartosz Sztybor was born in 1984 in the most dangerous neighborhood of Warsaw, Poland. As a kid, he dreamed of becoming a gangsta rapper but eventually became a writer instead. All Talk is based on his time living in Kreuzberg, Berlin, a multicultural district with many Turkish and African immigrants. He writes comics, films, and TV series (Cyberpunk: Edgerunners, Netflix) and works as a Comic Book & Animation Narrative Director at CD PROJEKT RED, creator of award-winning games like The Witcher and Cyberpunk 2077. He also writes The Witcher and Cyberpunk 2077 for DarkHorse Comics and has received multiple awards for Best Short Comic from the Lódz International Comics Festival (MFK). In France, his comics are published by Sarbacane, Paquet, Ankama, and Europe Comics, and in the USA, by Boom! Studios and Dark Horse Comics. His films have won numerous awards around the world. Although he loves writing, he dreams of becoming a gangsta rapper one day.
