Silent Hunter III features a fully dynamic campaign. Instead of giving the player a specific set of objectives for each mission, Silent Hunter III simply assigns the player a certain patrol grid, and appropriate naval traffic, such as convoys, destroyer escorts, and task forces are automatically generated by the simulation engine. How the mission proceeds and what targets are attacked is left totally up to the player. In addition to being a more accurate representation of WWII U-Boat warfare, the dynamic campaign significantly improves the game's replay value, as the campaign plays out differently each time.
The patch 1.4 for owners of the DVD version released in Europe, Middle East and Asia.
