Its a nice game but some features are a bit anoying. Torpedoes are duds way to offen. Game has a serious "hitbox" bug that offen disallow to disable/destroy ship weapons with cannon fire. I know that things are well armoured but i don't think it can withstand multiple direct hits wiht AP shell from less than 100m. You can hit shore if you badly set course on nav map. Crew is too dumb to recognise that they are going to ram beach. If you can live with this its best sub sim ever.

I don't fly the commercial junk,me and my kid play "Tig/catch up" with Fast movers over England and Wales,because Scotland hasn't been done yet,we both set off from RAF Marham in Fast movers and see who can reach the Base of choice first,without crashing or running out of fuel,and as low as possible!!
