Includes the original Subwar 2050 and its expansion, The Plot Deepens.

The year is 2050. The ocean is the next frontier and war inevitably reaches the depths of the sea. As an independent mercenary working for a corporate conglomerate, you pilot the latest fighter subs to protect the corporation's interests in exchange for cold hard cash. With 5 different theaters of operations (of varying difficulty) and an interesting mix of aerial-style submarine tactics, you'll be fighting fierce battles for corporate territory beneath the waves. 

The Plot Deepens is an expansion disk for Subwar 2050. It features a few new subs and weapons across three new campaigns: the Bermuda Triangle, the Mediterranean and The North Cape. In each of these campaigns, you'll launch your attack sub from its home carrier to protect the interests of multinational corporations engaged in mining, research, and development under the sea. 

• Pilot four types of submarine including deep-sea exploration vessels, reconnaissance subs, and highly maneuverable fighter submarines.
• Explore thousands of square miles of accurately mapped 3d underwater seascapes in four different multi-mission campaigns: the Antarctic Ocean, the North Atlantic, the South China Sea, and the Sea of Japan.
• 'Simulated Combat' mode lets you master maneuvers such as Knuckles and Deep Dives before entering a mission.
