There is a bug in the game: at some point after the Vavilov complex, Nechaev will get to Volan, where he will not be able to activate the device due to missing codes. In the future, you will go downstairs, find the house of Baba Zina and receive codes from her. But what to do if nothing happens when interacting with the Volan? Quest not updating?
The only way out so far is to use the debug mode, and such an error occurs, apparently, only for those who downloaded the pirated version that appeared on the trackers a few hours before the release. In debug mode, you need to press ALT + Backspace.
The action game also received a content update.
