Excellent sub sim for playing – lacks some technical scope of Silent Hunter 1 and 2.
Great graphics. A 64Mb Geforce will cope but you need P4 or equivilent and 128Mb graphics to play the graphics at full capability. Less will slow down when screen gets really busy.
It would be BRILLIANT if it had the torpedo adjustments and fine tuning from Silent Hunter. Be prepared to do some vector maths if you want to hit long range targets. At this stage I've really only done the subs – I found surface ships harder. The choice of ships is enough (sub/surface), though I wish there were more. Having started at Silent Service II and progressed through you pick up a lot of understanding about how things work – and it all helps here. AI is aggressive and great to play.
