It's been four weeks since the Green flu's widespread outbreak started. In the rising ruins of Avery, Colorado, four survivors found themselves trying to overcome the new strains of the infection and their mutual animosity for the sake of one single nearly impossible goal: To survive. Will their bonds hold together or will they turn on each other?

In this moment of upheaval, the veil between life and death has been disrupted, and the forces of darkness have seized an opportunity to manifest. Round, a fictitious small town set in the state of Montana, once vibrant and teeming with life, now lay in ruin, infested by hordes of the dead. Together, a group of four survivors dared to face the bloodthirsty wraiths amidst nature's frosty wrath and fight their way out of the damned land.
