Der Autor der Bücher auf denen die Spiele basieren, wurde in Russland in Abwesenheit zu 8 Jahren Gefängnis verurteilt. Er sprach sich gegen den Ukraine Krieg aus.
Glukhovsky was found guilty of posting texts and videos on his social media channels that accused Russian servicemen of committing crimes in Ukraine and that Russian prosecutors said were fake.
In April 2022, when he was already outside Russia, Glukhovsky wrote that the war in Ukraine, „unleashed by Putin is becoming more terrible and inhuman every day, and the pretexts under which it was started look more and more insignificant and false.“
