Plot: In the year 2051 AD, the United States had finally given into an ancient savage way of expansion known as Imperialism. For years, political officials had tried to execute imperialism secretly, achieving it indirectly by saying that the other countries were in need of liberation. However, since the people of America were ignorant of their true intentions for some reason, the political figures were soon able to achieve a state of mind which the American people were soon able to accept: Imperialism was righteous, since the rest of the world was not Christian.

Once the government had finally achieved this first step, the government began to drastically give all of its money to the construction of nuclear missiles. As the years passed, The United States began to drain the rest of the world of their natural resources until all military forces in all countries were no longer a threat to America. Some countries tried to fight back, such as Russia and China. However, The United States was able to subdue them. Europe's prime minister, however, was in league with the United States and allowed Europe to stay submissive to the wishes of the United States, causing a civil war. However, in the end, this just weakened the country for an assault.

In no time, an entire fleet of ships were armed and ready with nuclear missiles. However, the government had upgraded the weapons so that, instead of causing mass destruction, the missiles would only unleash radiation upon the population targeted. On March 13th, 2072, America unleashed the new missiles upon the entire world at 11 pm and by 11:20 all life was eradicated. The next few weeks were then dedicated to the transportation of the entire U.S. army to the various continents. After the soldiers had been successfully transfered to these various nations, the reconstruction of the countries soon began. However, the separate armies were not expecting what was about to occur...

The radiation caused by the massive nuclear holocaust caused massive devastation. However, it also mutated the dead bodies to become zombie-like creatures. And in a few days, the various groups of the U.S. army were attacked by these creatures. Unlike zombies, these creatures, which were soon called 'The Grateful Undead', were able to function like humans. However, even though they were dead, the combination of the chemicals and the radiation made it so they were able to "live". And in no time, the entire army was irradiated by these insane creatures, for there was no way to kill them. The only way in which they could be stopped was if they were blown to bits. However, since most bombshells had been scrapped to make these new nuclear missiles, there was very little that could actually execute such a plan.

Once each army had been destroyed, the Grateful Undead boarded the ships and set sail to The United States. Unfortunately, neither the officials nor the citizens knew of what as coming until the creatures left the ships.

The next few months was full of horror, as the creatures rained down upon the American public. Several things were tried to stop them, however, nothing worked. In the end, the government decided that The United States and the world was lost: they had to start anew. And the only place which this could be accomplished was the moon. Before, in the year 2049, NASA had created a space ship which could transport the necessary materials to start life on the moon. Using this as their escape tactic, thirty military officials, launched into space and soon landed on the moon.

Once they had landed, the officials began to create a new city on the moon. However, little did they know that some stowaways had made it onto their space ship....
