Left 4 Dead

The outbreak happened in the fall of 2028. They called it the cis virus. Only the transgender were immune.

The cisgender became the walking dead. I guess it was our testosterone and estrogen levels that made us immune.

But it doesn't matter why we were the lucky ones. If you can call it that, sure we escaped one hell, only to be thrown into another.

Damn.

So what's your name? Riley. I don't know how long you've been chasing me.
