Project ZPV02

This is Dr. Dusting speaking, ordering the emergency lockdown of the lab. If you're reading this letter, it means you're the humanity's last hope -- the stream of light in which is meant to save the world. Not so long ago, an experiment, a horrible one, has took place in lab -- and finding in which it've been wrong, too, perhaps, that is ain't possible in which to take back -- zombies, my dear reader, got spread. Though fear not, since immunes, reader, were all there in which to block the evil plan.
And, well, if it is you, Collen, who's out there reading this letter -- please, if you may, don't dare in which to open the Pandora's Box. I loved you, my son, and I always will.

Signed, Dr. Edmund James Dusting

Collen wakes up in a lone chamber with tones of piled dead bodies, and reading the letter in which was written a while ago -- a hand emerges from the ground, grabbing his armpits. It tries to bite him, scratch, and cause destruction but fails. What was it? He asks himself, his face blue and pale. But as he takes glimpse of the window in which leads outside, thousands, or millions of, well, them, the zombies, were spotted.

You are humanity's last hope, the light.

Go, hero -- go save the world, go to where in which the danger is.
