You are a Necromancer. In fact, you are a particularly dangerous one, as you are a Necromancer with a business plan. Your zombies will dig up and loot valuables from graves, and while they're there, they can also grab fresh body parts so you can make MORE zombies to dig up MORE graves. Sounds good, right? Unfortunately, it's so good that other Necromancers are now competing with you for the choice cemeteries!
Players start with zombies of varying values. They take turns placing zombies in specific location to "dig" up graves, steal from opposing laboratories and vaults, and to attack other player's zombies to try and prevent them from digging or stealing (and possibly dismember the opposing zombie beyond further use).
Once all the zombies have been placed, zombies still in position will steal body parts or treasure from opponents, and those set to dig will dig the row, column, or specific space of the graveyard they are assigned to. If you are competing for spaces in the graveyard (which is the norm), players compare the combined brainpower of their digging zombies, and the higher value gets to the contents of the grave first.
Then you may use your new-found corpse pieces and equipment to assemble new zombies to do your bidding!
The goal is to have the highest total in treasure and unused body parts at the end of the game.
