Rising up from their graves, a mass of zombies driven by a pang of hunger, not for flesh, but of impulse, makes its way to the land they once called home. In hoards, the undead militia descended upon the city as memory fragments drove them to take back what once was theirs.

In fruitless chaos, both hordes slowly destroyed each other, not knowing they were the same.
