Grave Days is a game about surviving the Zombie Apocalypse. The game emphasises contrasts. It focuses more on action-packed fun rather than strategic-realism in terms of gameplay, though is still a survival game rather than a shooter. During the day, it is more of a typical survival game with building, crafting and exploration - whereas at night, it turns into an atmospheric horror. It tells the story of a survivor named Grave Dave, and his struggles in a world where society has collapsed under the weight of a Zombie Apocalypse.
