Something that appears to be a virus was discovered. We just took a sample.

The virus from up close... strange, huh? No wonder no one knows where it came from or how it got here!

Oh no, it began spreading. They're getting infected.

The symptoms are horrible. We were able to capture this image of a human mutating. Wonder what it does to the brain...

Let's get out of here before they notice us. What the—shhh!

"Can you hear them?"

An abandoned city. All of the survivors are escaping. People have been infected, and they are forming an army.

We're heading to the city to look for further clues. Wish us luck!

What could it possibly be?
