America 1860s. Once a bustling nation, now under siege from itself. The trauma of the civil war where thousands upon thousands of men, women and children died, Nature decided it was time to fight back.

The dead rose and swarmed across the land like a never ending storm. Those who would've sought freedom and a new life out west, now only seek survival.

Nature didn't just punish the land of it's cruelty, no it also enhanced it. Wildlife evolved and grew into sentient humanoid beings. The nation's first people who lived off the land prospered.

Will the American dream wither before it can take root?
