Writing via Facebook, 11 Bit's message was simple: "#FuckTheWar".
The studio had previously said it would also donate all proceeds from the sale of anti-war game This War of Mine over the past week to the Ukrainian Red Cross - one of several developers with similar initiatives.

"Buy This War of Mine anywhere and support victims of war in Ukraine."
