The year is 2097. In a vain attempt to fight back against the waves of terroists sweeping across the continent, the USA developed a new virus, in the hope that it would give the army an advantage. Instead, the virus found a carrier before it was ready to be unleashed onto the villans. The infected man started to mutate, developing a taste for human flesh. After one week, the virus had spread across the entire world. No one was safe from the hoardes of 'Zombies' that now stalked the streets. But mankind would not die without a fight, and groups of survivors made camps on the tops of buildings, and in other easy to defend places. The 'Zombies' were renamed Human Mark 2 by the scientists who created them, and who were determined to destroy them...
People who have come back to this page will notice a change in the story. I decided to make it slightly longer, and add some more detail.
25 days after the virus spread. 3 cops are caught up by a group of Mark 2 Humans, and one of them is pulled down by the pack. His two partners try to save him...
Ratatata! Alas, their efforts are in vain.
Say, explosive barrels?
Some zombies get hit.
A green explosion?! Man, thats some freaky stuff!
All the zombies. The guy in white armour is a scientist from the lab that created the virus. The guys in grey are people who worked as gaurds there.
Update. It would seem that the virus, as well as mutating Humans, also reanimates dead corpses that are still in a reasonably intact condition.
