War, war never changes. The faces, names, and weapons have changed from the dawn of time to the modern era. When the world made the ultimate weapon, they marveled at their brilliance without thought of consequence. When the doors guarding the secret of the atom had been unlocked there was no way to hide it away again. The proverbial Pandora's Box had been opened and its terrible contents unleashed upon the world. To abate the worries of the population one company created underground structures known as Vaults. Space in a Vault came at a premium. In the case of a nuclear war they would shield those within so that at least a fraction of the human race would survive a Nuclear War. They thought it was the last World War, when the power of suns rained down upon the world scorching the land and leaving it a radioactive wasteland. But war never changes, and it never dies. Now a new war begins, one for survival. The weapons and purposes and names may change, but war never changes.
