Good stuff ! Here's a few quick general tips for the North Atlantic.


- at 180 meters depth, if not on silent running your boat cannot empty the bilges but it also will not take on any other water. Your pumps are at equilibrium with the water pressure at this depth.
Any deeper, you will slowly take on water and gain depth if on silent running or you will have to use compressed air to empty the water out if not on silent running. <- this noise attracts undesired attention from any escorts nearby.

- at 150 meters depth or less, your pumps alone can deal with any water that leaks into the boat (from non-damage sources only). Also at this depth, your pumps will slowly expel any accumulated water; compressed air not required.
NOTE: If on silent running, eventually at any depth your pumps won't be able to keep up and you'll take on water and gain depth, but it takes longer the shallower your boat is due to the difference in water pressure.

Your Chief Engineer will inform you of the status of all this when necessary, along withe the "g" key gauges.
- be careful with your periscope. It WILL be spotted if careless and it takes a much shorter time than in SH3, i.e.
- when wanting to avoid escorts, go deep but keep an eye on the water level in your boat per above. Use silent running only when absolutely needed vs. on all the time, because of the water issue.
Depth, speed, and course changes are the key to dealing with AOD escorts, usually all at the same time.
- use the map screen to keep track of escorts when you're submerged. Go to 500 meters or less magnification level.
This allows you to see which escort(s) is closest to you and what they're doing via the movement of the red bearing lines showing their relative position.
- AOD has a very detailed damage model. DO NOT casually deal with leaks/flooding warnings due to damage.


More later if desired.
