After i read this:

I came up with this: Summary- New York City is under quarantine due to a break out of a virus. A virus that is spreading through by something simple like a bite. The citizens of the city are either hiding, preparing to fight this chaos, or dead. What happens to people infected with this Virus is a disease that destroys the chemical in their brain's called Serotonin, which changes them into pretty much a zombie. And here's the worst part. These "Zombies" might be heading to the sewers soon. So the TMNT and their allies have something very interesting to go up against.
And I will get started on this story soon.
