Blood Money is set during World War II, where the player takes on the role of a soldier searching for lost treasure and avoiding enemy fire. The story follows a single-minded quest for wealth, with little concern for the consequences of one's actions.
The gameplay in Blood Money revolves around navigating through scrolling levels while fighting off enemies. The ship can be upgraded at designated shop rooms using earned money. Energy is depleted by contact with enemies and obstacles, adding a time constraint to the game.
