After weeks of escalating tensions, the Russian invasion of neighboring Ukraine has begun. In response, the developer of the anti-war indie game This War of Mine will be donating profits to the Ukrainian Red Cross to help Ukrainian civilians caught in the crossfire.

11 bit studios, developer of both This War of Mine and Frostpunk, announced on Twitter that it stands against the Russian invasion, but that words were not enough without “a meaningful act.” That’s why the studio will be directing all profits from sales of This War of Mine over the next week to the Ukrainian Red Cross to “directly support victims of the war in Ukraine.”
