Overall, it's a good game, but the way that the campaign and encounters are done lack both variety and sense, especially when you start a "battle" 10 km in front of an enemy surface fleet, ruining any sort of surprise.

Still a good game, but feels a bit unfinished and unrefined.

Consider "Sea Power" for larger ship, plane and sub sim, although much more basic sub to sub combat.

The learning curve is really steep, controls are janky, tutorials are not very convenient. Why make a game so complicated only submariners can play?

Silent hunter but cold war? something like that, this game will easily bring you into the mindset of the commanding officer of a nuclear submarine. When first starting, you may see some scenarios as The Kobayashi Maru as you react, but this is about the cold war gents! This is the game of cat and mouse! Have they detected me yet? or have they only detected my torpedos on their way to them? Should I salvo some harpoon missiles before that warship gets too close? Then the sudden air drop torpedo that scrams your reactor and leaves you dead in the water makes the choice for you. MISSLES AWAY! As soon as your reactor comes back online you ring up ahead flank just in time as more torpedos splash behind you, you drop a decoy and launch more torpedos in the direction of the enemy fleet, your sonar reports good hits and vessels breaking up from your first salvo!
