One time, in the stormy cursed area of Krunkerville, they existed a "school" as we all thought it was, named "Krunkerville High", but there was somethings unusual about it...
The "students" in the school are actually a species of aliens which we call "Kruncanites", Very few existed a first, but it turns out they had a cloning machine, so as time went on, they kept getting cloned, increasing their popularity. The Kruncanites Speak a language known as "Kruncrarian", which takes years to speak fluent. Kruncanites are all the same, they're all obsessed with techno music, modern gadgets, mobile phones, cigarettes and drugs. The Kruncanites live in a planet known as "Kruncia", it's the 9th planet away from the sun, it was origonally descovered in 2003 as "Planet X". The planet is full of pollution, radiation and cigarette smoke, so much so, that the Earth's atmopshere is too clean for the Kruncanites, so they use Cigarettes as breathing masks. The Kruncanites appear to have a very low average I.Q., the think anything that resembles a cigarette (for example; a pencil, or a rope) is a cigarette, so they try and smoke it, it take combind brain cells to figure out it isn't a cigarette, it's the same story with Calculators and Mobile Phones.
The Kruncanites bodies are 60% "Kruncrarian Slime" instead of water, Kruncrarian slime is a chemical, a drug, you could say, if even a drop touches you, you'll become one of them, it could spead like raibies. The Kruncrarian slime can not only affect humans, but dogs, and posibly other animals as well. A fellow rossi comrade got his lip bitten off by an effected dog.
As you might of guessed, the stuff had speraded all over Glasgow, then Scotland, then the whole of Europe, then the rest of the world, becoming a global pandemic, they are few survivors left...



...And this is the "mastermind" beind all of this, Emporer Yunki! He's now evolving the slime for the new decade, it will transform humans into kruncanites fast, and the chance of survival will lower, once he has everyone turned into a kruncanite, he will turn planet earth into a giant fag, and all the kruncanites will fight to the death to decide who smokes it, the survivor and winner will become the new emporer, we must stop all of this and restore Earth back to how it was before this invasion, by destroying Emporer Yunki...

You will play as a survivor Rossi comrade, one the remaining few, who is equipped with a dart-gun modified shotgun, that's all you have though, but that's all you need...
