If you are into military planing, tactics and strategy and into naval battle you will love this one...
You'll spend hours chasing and hunting down warships and commercial ships, avoiding attacks from destroyers but same time sending powerful torpedoes to your targets according with your missions orders.
It is not a "clicking fest" it is more mastering full control of your submarine and crew and how to silent but deadly destroy your enemy.
It is very entertaining and rewarding, money and time well spend...
Because of this game Ubisoft is now on top of my favorite list...
If you still wondering if you should buy it, if is worth the money, or your time, don't waist time no more... find this game, install it, learn the controls and I am sure you will not be sorry...
