The Aliens were on a mission to disprove the existence of extraterrestrial life. They failed. They crashed into Scarborough due to a silly calculation error and, after releasing total chaos on Earth, they managed to flee to Antarctica where they built a new home in the ice.

They are two foot wide, featureless grey balls which manipulate objects by contorting the forces of nature around them. They interconnect into various formations to move and communicate telepathically. They breed by... to be honest, no-one really knows how they breed, but they do and with numbers swelling, pressure is on to get back to the ship and get home.

The unfortunate fusion of Human flesh and Alien physiology, the Zombies are technically dead but still find the means to complain about being perpetually hungry. They have not helped themselves much, choosing an extremely limited diet consisting of leather, feathers and breakfast cereals and putting in very little effort to avoid the inconvenience of ‘innard-freeze’ in the European winter.

By some fluke, however, they happen to be partially telepathic and one, who is less intellectually-limited than the rest of his kind, is determined to find betterment. He leads them into the North York Moors on a quest for enlightenment.

Initially released as human-controlled war machines, the highly-intelligent Bots soon learned that eliminating the Zombies they were programmed to destroy was tedious work. After detaching themselves from human control, they turned instead on their former masters for more of a blast.

Now, they are led by a little computer with big ideas. After destroying the human's entire digital system, and with it the fabric of society, it is intent on taking control of the entire global system... including nature itself. It doesn’t love others describing its grand plans as 'evil', but then given how superior it is to everything else, it doesn’t really care.

In the chaos that followed the Alien spaceship crash and the Zombie virus which followed, the humans fled Europe and Africa in droves across the Atlantic. Now tens of millions of refugees are camped on American shores stuck between the hostility of unwelcoming American hosts and a homeland overrun with Zombies.

Two British teenagers are the unlikely catalyst for action as the European Royals try to advance their efforts to build a force to sail back across the Atlantic and reclaim their lands from the Zombies. Being bereft of technology makes things all the more complicated, however, and it’s fair to say their hopes for a quick and easy answer are optimistic to say the least.
