What can I say, well first of all I wasnt drinking yesterday, but I didnt get to bed till noon today, spent all night wringting scripts and watching good old movies, like ALiEN and DasBoot.
In Enigma, the sub detection by the AI is 100% the same as for the player.
They dont know:
A: who you are (friend or foe) till they are close enough to identify you.
B: where you are unless youre caught on their sonar thing (which I cant remember the name for right now)
C: what your depth is, they base their depth charge dropping on tactics, there is no AI cheating, like they knows your depth.
D: what your heading is unless you play on EASY mode and they are within 500m cause then your red dot turns to a red triangle on their tactical display like they turn to triangles on yours.
A few sub tricks:
A: never submerge below 20m (unless forced to by a vessels sailing ontop of you)
B: Hold your fire till the very last moment.
C: if you must dive, then change depth and course often
D: the deeper you are and the closer to you they are slow your speed.
E: when they drop charges, then speed up and when the last explosion is over speed down.
F: at periscope depth they can hardly find you, so use max speed.
East told me once that if you can hide for 10 real life minutes without being blown away, the AI will assume youre dead.
100% stealth is not very fair to the AI cause they would never find you, and if you turn it around, its unfair to the player if the AI can hide themself 100% from you
A few notes on the patch.
Easy vs Diffecult, is still the same, you play on easy, so does the AI, you play on diffecult so does the AI.
The missions in the campaigns are very player friendly now.
Starting point in game, is a bit changed.
In the random patrols as Bux said, you can control mother nature, but not what you want to face in combat, however you can select a random corvette patrol and choose to steer out in a destoyer (or a battleship if you have completed atleast 1 full campaign).
Hope that helped
