U-Boat Missions is the first official add-on for Silent Hunter 4: Wolves of
the Pacific.

In 1943 the Japanese High Command requested that the Germans send a few of
their submarines down into the Indian Ocean and the Pacific so the Japanese
could study their techniques and the supreme commander of the German navy,
Karl Donitz, granted the request. So on September 1943 the first five so-
called monsoon-boats entered the harbor of Penang.

The new German campaign gives the player the command over one of these Type IX
D2 long-haul submarines and sends him on patrol in the Indian Ocean and the
surrounding areas to fight the American convoys marching through that space.
The player can also take control over the Type XVIII Walther with it’s
revolutionizing air-independent propulsion drive. The add-on also adds several
new warships, merchant ships and airplanes on the list of possible targets.
These include famous warships like the Cruiser Admiral Graf Spee or the
merchant ship War Melody.

Other changes include the increase of the render distance to 20km and the
addition of new player and crew abilities to the crew management-screen.
