I've been waiting for this game since 1998 when the first sub sim (688i hk) was released by sonalysts! The wait was worth the result we see in "Dangerous Waters". The first challenge is mastering the 7 different platforms (air, surface and sub surface) this sim provides you with. Once familiar with the intricacies of each platform you can then turn your attention to tactics strategies and team play. An average "dive" (as a game session is called) can take anywhere between 1-5 hours, patience is a virtue as time is spent listening to sonar and zigzagging your sub searching for hostile contacts and hearing whales and shrimp instead! Once you get a trace of a "hostile" or hear "torpedo in the water" the pace picks up, adrenaline starts flowing and the action begins! Am I the target? Should I run? Should I fire back? Each of these questions has a different answer each time you head below the waves; no dive is ever the same.
The aircraft on this sim (MH-60R and the Orion P-3C) are far from being modeled according to even basic flight simulators. You "fly" for the most part by adding waypoints or typing in the altitude, direction and speed. Time spent is looking at your sonar buoys and various other sensors searching for hostiles.
There are a number of online fleets who actually have "dive schools" that show new divers the A's through Z's of basic platform handling. This is a great way to find sparring partners and to learn more advanced platform handling and tactics - This is where the most rewarding dive occur.
I wouldn't recommend this game for those of you who are into the quick point and shoot action games; it just doesn't work that way. It is however extremely rewarding for those of who can implement tactics and execute strategy. In short Naval Chess!
