I've played all of the Silent Hunter versions and must admit that I find CW on par in most respects and very enjoyable. The game is very atmospheric and keeps you coming back for more. There seem to have been several updates since it was initially launched which could mean it wasn't quite ready for release or the developers are keen to enhance and expand its capabilities. Either way, I look forward to future updates to this very engrossing sub-sim.
The product says "TO PLAY THIS ITEM YOU ALSO NEED - COLD WATERS" so I assumed this was enhanced audio for the game. Turns out I was wrong, as the audio tracks are just HQ standalone Original Sound Track recordings of the music used in the game. If I had known this I would not have purchased this item.
