In addition to providing a whole new experience apocalyptic Red Dead Redemption: Undead Nightmare splits completely new treasure maps. Six in number, this video explains the position of the various boxes on the game map!
NB: The first box does not contain a treasure itself. Looking for a makeshift camp, any, and search the trunk normally placed beside that contains your first treasure map! If the boot does not have a card, make sure you didn't have it already in your inventory (Probably retrieved from a previous plunder).
