Naval Ops: Warship Gunner 2

The game is set in 1939 of an alternate universe, and thus combines technology of this period in the real world with a variety of futuristic lasers and weapons, without the "World War II-only" mode of the first game. The story follows three or four officers of a Wilkia Freedom Forces naval crew as they lead the resistance to the coup that overthrew their King, then declared an Empire led by Admiral Karl Weisenberger and started making war, in a manner akin to real-life Nazi Germany.
