It has been twelve years since the dead began to walk. The Earth is overrun with the rotting corpses of humanity that swarm through the lands and devour everything in their path. The cities have become graveyards, their tall buildings morphing into giant, crumbling tombstones that watch over the carcasses of civilisation while small clusters of the living hide amongst the ruins. The base is surrounded and running low on supplies, ammunition, and above all...hope. As the people within the fortress walls slowly suffer the same fate that has befallen the rest of the world, they realise that the time has come for them to leave. Under the leadership of Tina, the survivors must confront their worst fears, and venture out into the infested wasteland to find a new place to live before it is too late. Stan and his men are also searching for a new beginning. With virtually nothing left for them to scavenge during their raiding parties to the shore, they need to look elsewhere, but they cannot do it alone. Seeing no other choice, they launch one final and daring mission to the mainland in a bid to ensure their continued survival.
