Decades have passed since our world was destroyed. Some say it was an act of God. Others believe that the devil himself breached the gates of hell and turned the masses into mindless humans, infected with a lust for carnage. Those of us who survived the Calico experiments know that the only thing scarier than the monsters bent on laying waste to what's left of us is themselves. these are the people who created them. Those who are all too capable of hiding their true form and burying their darkest secrets. Somewhere beneath this structure lie the answers, the cure to our suffering. To get to it, we will have to open a ghostly tomb where the deadliest mistakes of man, the most cruel mutations, are imprisoned in its tunnels and waiting to be released.
