The end of the world, or is it?

You awake in a small cabin, no one's home but you and yourself. You have no memory of this cabin, or even getting here. All you know is that something went wrong in a lab 3 years ago, causing a outbreak of zombie viruses and mutations resulting in many types of undead.

From here on out, this is your story, be a hero and find a cure, try and find surviors, or fall to the hands of undead. The choice is yours.
