Pacific Storm.

[Kapitänleutnant Erwin]

There are two types of campaign modes, one that starts pre-1941 and the other starts at the beginning of the war. In the pre-war mode, you have until late 1941 to have your country ready for war. One vital aspect to the game is to maintain your supply lines. As in the real world, your ships only have a limited sailing distance, so you need to build refueling points (and defend them). Building a base is more than just capturing a point on the map--you need to build barracks, warehouses, fuel storage facilities, base defenses, and an airfield.
