Well it aint that hard, In a practice mission with autocrew off i created i sunk a Nimitz CVN and a AUS Colins sub for practice, but i forgot that i also had added a US Seawolf, so after I fired my torpedos i had given myself away, next thing the seawolf fires a torpedo, from about 15miles away i evade go deep but not that deep cos a kilo is limited to only about 350feet - could be wrong here but im sure she is a shallow hunter. im hearing the pinging getting louder and louder... im letting of countermessures.... im zigzagging, i know i'll go quiet that'll fool them...boom! im dead

.
Commanding a Kilo Improved SS diesel boat probably isn't the ideal sub to start learning the game with, i think the diesel and having to go to snorkel depth to recharge batteries she kinda reminds me of a XXI, is what attracted me. Also targets can be detected from only 10miles approx but anything longer could be tricky, from my experience, yet im still learning. The Kilo is very quiet.
So ignore the graphics, this game is all about hrs of sneaking around or game over man in 15 min. Plus the Editor is very very good.
