Dangerous Waters is an in-depth simulation of modern submarine and anti-submarine warfare (ASW), with a particular emphasis on realism. As the direct successor of Sub Command, Dangerous Waters entitles you to command the most advanced nuclear submarines in operation: the American SSN-21 Seawolf-class and 688i Los Angeles-class, and the Russian AKULA-I IMPROVED and AKULA-II. Additionally, you will be able to take control of the variants (Projects 636 and 877) of the KILO-class diesel-electric attack submarine, a ship which lacks the endurance, speed an power of its nuclear counterparts but which is particularly quiet when running slowly and deadly in shallow waters.
