Haha! They wouldn’t Blitz anyway! They would just inexorably advance across the globe, huge stacks of Zombie’s pushing across the Siberian wilderness, down into India, and….floating across the pacific in slow moving hulks?
Alliances would fracture as the Russians, the Japanese, the Chinese, and the FEC all get pushed back by Zombie hordes. The German War for Leubensraum dies out as the forces of Zombie creep into Moscow. The Russians, panicked by the Zombie pressure behind them, push into more defensive territory in Scandinavia.
The Chinese refugees flood into Iraq and Turkey. The FEC has fallen with the bloodiest deathtoll ever seen.
Island nations, like Japan, survive only by stringent dictatorial security, and martial law, but they have been cut off. Every day, bloated diseased bodies wash towards its shore, bringing outbreaks of the disease. But they survive.
Germany prepares. It has mechanized and armored every division. They have built the Krankheit Line, and intend to hold it. Yet still, America threatens to land in France. Britain aggressively probes its Air Defenses.
:-P
Hehe fun stuff.
