A grim alternate history where WW1 ravages the world, pushing technology to its limits.
Russian guy: Imagine if: The year is April, 1969. WW1 ravages Europe, reaching the Americas and Asia alike.
Technology has been hyper-driven by the never-ending war, the Allies are exhausted, cold war technology is pushed to its limits in the muddy concrete bunkers and no man's land.
Russian guy: A whistle rings through the German trenches, another desperate charge. No one knows how many lives have been lost now. German armor rolls through barbed wire as they finally take a British trench, artillery shelling them throughout the charge.
