In the game, you will take on the role of a guy who’s been thrown into a world of ghosts and zombies. His only hope is to build a fortress, find a way to defend himself and his family, and defeat the onslaught of evil spirits.

To help him do that, he has access to a large arsenal of weapons, armor, and other items. But the first thing he needs to do is to find a place to build his fort. And in order to do that, he has to explore the different parts of the map and find the places where the zombies and ghosts are concentrated.
