We almost that have finished job rather icebergs problems.
Now behavior more correct: they are seen on HF sonars.
(In original game HF sonars are broken, you can not see on them icebergs [malicious gift from SCS -
] )
Physics more RL: The torpedos and missiles - not can penetrate icebergs, as through butter piece.
Now, at collision with iceberg, the submarine crashed, instead of iceberg.
But some tests are required still.
It will make battle under polar cap, extremely realistic and difficult.
