Developer Mundfish has come under increasing scrutiny in recent weeks after it was alleged that the Russian government stands to gain financially from the release of Atomic Heart. This is due to the fact that investors involved in the financing of Mundfish include GEM Capital, an investment fund whose founder has ties to Gazprom and VTB Bank, both of which are majority-owned by the Russian state. 

Mundfish is also partnering with VK (formerly Mail.RU) for the Russian release of Atomic Heart, evading sanctions on Steam – VK is also majority-owned by the Russian state through Gazprombank, and Mundfish’s CEO is a former Creative Director at Mail.RU.

With Russia’s ongoing invasion of Ukraine, many players are now choosing to boycott the game in protest and donate money to organisations like The Ukraine Crisis Appeal, International Rescue Committee, and the British Red Cross.
