From the publisher:
You have just become the manager of the warehouses for a major crime syndicate. It is your job to fill the needs of each warehouse according to the contracts of your clients. Make sure you fill the orders, your clients don't take kindly to failure. Oh, and watch out for the cops!
The goal of Black Market Warehouse is to score more points than your opponents by fulfilling warehouse contracts. Each warehouse contract will require a certain amount of black market items. If you can fill the warehouse with each type of underworld item it requires, you cash in the warehouse and collect all the points for each item, as well as the bonus points for the warehouse. You can also play cards against your opponent to slow them down, or help you succeed. When the warehouse cards are all gone, the game is over.
