Frank survived one expedition out into the world, but he'll need to do it many more times if he wants his people to survive.

He starts by searching for another of the rare working vehicles still on the road. More cars mean more supplies.

Every trip out comes with risks. He soon finds abandoned military roadblocks, competing bands of survivors, and average people getting ever more desperate.

When he stumbles on a group of teens still hunkered down at the high school, he comes face to face with the grim reality stalking them all. It will soon be 'kill or be killed' throughout the land...

Frank saves who he can...

His group continues to grow.

Before the end of the day, Frank will learn of the dark forces already lining up against him on the outside.

Someone out there has seen what one man can build, and someone out there would like nothing more than to knock it all down.
