Through the use of Action Cards and random NPC cards, the danger levels can change from moment to moment matching you character's growth from rookie to "00". As you progress, you gain Action Codes that can change the course of the adventure, bringing surprises and thrills you never thought possible with a solitaire game. On Her Majesty's Secret Service contains FOUR complete adventures that can be played individually or linked together, using James Bond or a character of your own creation.
