At the various surfacing cities, the player must try to convince the agents to turn over their piece of evidence. Initially the player only has $5,000 to bargain with, but their arsenal of items grows over time and bargaining. The real challenge of the game is determining what each spy wants and how to get it for them. Eventually, all the spies' whims can be satisfied for all the pieces of the secret document. Note that different copies of the game, even on the same computer platform, have differences in which items the spies want.
