Yes, the game is surely fun for the action you get when making evasions or attacks, there is an 'action camera' showing everything if you like.
But the game is far from playing in arcade-style, most aspects of a submarine are simulated quite well and you must use good tactics to succeed. Use naive techniques and you will regret it soon...

The campaign can last very long unless you succeed in every encounter, but even then it will take awhile until the opponent country is defeated. There is a moving frontline that changes according to how well you do in the war.
The game plays out like the classic 'Red Storm Rising' but with much better visuals and game mechanics. And with mods you have plenty of subs to chose from and you can play the opponent's side (and their subs).


To my taste the game has a surprisingly high re-playability, the battle situations are quite different each time. What the game does NOT simulate are the sub interiors and battle consoles although there is a periscope view and a damage section where you must take decisions to prioritize repairs. Else you have the choice between a pure tactical map view or a combined action view + reduced tactical view which you will see in most game videos.
