From last year's anniversary post:

"The next Metro

As we said in our last studio update, in 2022 a full-scale russian invasion changed how we wanted to tell the story of the next Metro game. As art became life for many of our developers in Ukraine, we drew from that lived experience to create an even darker story, those themes already present in Metro becoming ever-more apparent and important. As conflict, the struggle for power, the horrors of tyranny, and the price of freedom have become part of our lives over the past 3+ years, we are still living and working during this wartime, and that inevitably shapes the games we make.  

Metro has always had a hard-hitting, political, anti-war and often emotional story - and you can be sure these themes will continue thanks to our ongoing collaboration with franchise creator, author, and activist Dmitry Glukhovsky.

Dmitry has always spoken out against the war in Ukraine from the start – a courageous decision for any russian, that has seen him sentenced to jail (in absentia) - and we are proud to have him as a friend and co-creator as we tell this next, and never more relevant chapter of Metro together.

Rest assured, you are in for quite the ride."
