What i like in AOD are these moments, when you have looked around a convoy, saw no escort in it, and too focused on the convoy you have not made a 360 with your periscope.
So you decide to target one ship and begin to move at flank speed at periscope depth because you were a bit too far.
Then you hear some pings, followed soon enough by the sound of a destroyer engine roaming the sea and suddenly you see in the periscope in a different direction from the convoy :
And you hear "something" being dropped in the water, 3 or 4 times .
There are few games that can bring you into that feeling of panic mode
