What Lies Ahead

The year is 2055. Yellowstone, the great underground volcano, has finally shown itself to the world.
Only the western half of the United States and the southern half of Canada were obliterated. The rest of the world lived on.
But then something unexpected happened.
The fumes of the great volcano did something to people. It affected their nerves.
And their brains.
People started taking on zombie-like qualities.
Now people are forced to wear masks and be on the alert at all times.
Because now not only do they have to avoid breathing the toxic air, but they have to avoid the terror of the dead.
