How to Get Out on Hard Mode
What I did, turn everything off and put the blue light on. Move at slowest speed at periscope depth with you periscope hidden. Don’t get close to any ship, that goes for the idle ships as well. Make sure the boat is stopped if you need to check your surroundings using the periscope.
Then hide it before moving on. When in position, like 3 km from your target, fire all 5 torpedoes, preferably hitting the ship right at its side. As soon as the torpedoes are off, full speed ahead and crash dive to the lowest depth. As war ships move in to drop sink bombs just zigzag with some timing. If it gets too hot, steer away, stop the engine and rest on the sea floor for awhile.
Hopefully they aren’t aware of your exact location and you just have to wait out their attempts with the sink bombs.
At first I tried sneaking by the sea floor but that didn’t work very well for the escape.
From the sea floor, surface quietly with engines off to check if the coast is clear. Then dash the hell out of there. And mind the submarine nets ))
Oh, and do this at night of course.
Some stuff I did that made war ships come straight to my position was:
- Putting pump on
- Putting ventilation on
- Sending radio message
Now I don’t know if that caused them to hear me but probably. Try to avoid it.
