I was just a toddler when it all happened, when the world turned to shit, and now it's gotten worse. The virus that causes humans to enter a zombie-like state which has mutated is now airborne and is threatening to end humanity.

As a courier I deliver packages, usually filled with supplies, but this time I'm carrying a package of an up-most importance. The fate of humanity is now in my hands.

My name is Train Martin, a courier, and this is my story.
