What the store says
The history you know is not necessarily true. In 1944, the Allied Forces landed in Normandy, now referred to as D-DAY. Evil scientists used weapons that could change the weather, which lead to the battles in Normandy failing in the storm. In 1945, the Nazis set off an experimental Antimatter Bomb, destroyed most countries in the world, and destroyed social rule. This day is called Zero Day, Z-DAY in short.
