Dangerous Waters is, without doubt, the BEST naval/submarine sim I've ever played, and I've played more than a few in my day. The fine folks at Sonalysts really did their homework when they were creating this game, since nearly every aspect of it oozes a level of realism that you're hard-pressed to find in most other games these days. I truly believe that the gameplay you experience in Dangerous Waters is a very accurate portrayal of actual naval operations and procedures in practice today; every vessel and weapon you will encounter has been meticulously reproduced according to real-life records. Hell, I could probably operate my own Los Angeles or Seawolf-class sub singlehandedly thanks to what I've learned from this game regarding their operation. Let it never be said that videogames don't teach you anything.

This tremendous level of immersion comes at a cost, however. Dangerous Waters is not so much a "game" as it is a genuine training siumlator, and as such has an extraordinarily steep learning curve that simply can't be overcome without first reading the manual and running a few practice missions as tutorials. However, even that won't fully prepare you for what you'll have to deal with once you finally take to the open seas, where even a single torpedo is usually fatal, and a compromise in stealth can ruin an entire mission. Dangerous Waters demands patience, dilligence, and a certain enthusiasm for submarines from its players if they hope to develop any real skill for it.

Dangerous Waters is not for the faint of heart, but it can be a very rewarding experience if you take the time to learn the finer points of its gameplay. You may have to lose a boat or two or a dozen before that finally happens, but that's merely half the fun!

Do not buy if you are on Windows 8. Will not run and the company refuses to patch or support it. (I have never actually been able to play this)

Simply put: This is the greatest modern submarine simulator ever. This game is not for most people, because it is pretty hardcore realistic. The playable submarines are: Akula and Akula Improved, 688(i) Los Angeles Class, Kilo and Kilo Improved. (They also make a MH-60 Seahawk, P-3c patrol plane, and Oliver-Hazard Perry frigate playable, but those aren't nearly as fun or polished) The level of depth they went through to make this as realistic as they could is breathtaking. Going through Sonar to find and classify vessels feels very rewarding. Once classified, you determine the speed through the Demon waterfall. After that, you go to the TMA (Target Motion Analysis) station to put in all the info to fire a weapon at it. All this takes time and a lot of effort, as you have to remain silent yourself because the AI is doing the same thing. If you feel overwhelmed by all this, you can put on auto crew on almost every station, so you don't need to do everything yourself, especially if you're bad at it. (Like me at TMA.) The campaign is very hard, at least for me. But you can train up on quick missions which involve you sinking 1-3 vessels depending on the difficulty you choose. And there is a ten-digit seed generator which makes quick missions infinitely re-playable. Overall, I would give this game a great thumbs up and 10/10 rating. [At the time of this review, I have 37 hours on record.]

Hands-down the best modern submarine/naval combat simulation I've ever played. If you have any interest whatsoever in the genre, this should be your first and last stop.

do not get this if you have winows 8 or better. it doesnt run and the company "doent support" this game any more.
