Hint :
fire torpedo:

to fire a torpedo is easy. You dont have to go to the torpedo screen, just press enter, and away it goes

follow the torpedo with a kamara:
When you fire your torpedo, just press k and you will se if you hit or miss the boat.

Troubleshooting Tips

It's been five years since Silent Hunter gave you command of a US submarine in the Pacific, six years since Aces of the Deep thrust you into the Battle of the Atlantic.After a protracted development period which involved two dev teams, and several company buyouts and asset shuffles, SSI/Ultimation is proud to offer the new WWII subsim standard: Silent Hunter II.
Installing
Before installing Silent Hunter II, check your graphic card and sound card drivers with the latest offered on the company website. Up-to-date drivers are the biggest reason why some people cannot get their games to run and it is up to you to rectify this.

After installing, run the Configure program so the simulation can adapt to your graphics card.
Troubleshooting
Read the manual before announcing to the world you have found a bug. It could be part of the game design.




General
If you conclude a campaign scenario and the Summary says you failed to complete the Primary Objective the program forces you to replay the mission until you do. If you don't feel like replaying the whole mission, you can hand-edit the scenario file and remove the Primary Objective. This will allow you to skip it.

The scenario files for the campaign are located in the C:\Program Files\SSI\Silent Hunter II\Shell\CampaignFiles (provided you installed the game in the default directory). The files are .SDF files which can be opened and saved with Wordpad. Open the scenario you wish to bypass and look for the line:

;;; Objectives ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Now look in the first [OBJECTIVE] block for the phrase: Primary = TRUE


[OBJECTIVE1]

Objective = TONNAGE

Tonnage = 2500

Type = WARSHIP

Primary = TRUE

Score = 101

Simply backspace this line out and now the scenario has no Primary Objective. You may start the scenario and press ESC after it starts. Then return to the HQ Office and start the next missions. I advise you use this very sparingly. One, it will keep you from getting medals and promotions as readily, and two, it could become a crutch and speed you through the campaign at a fast clip.


Attack strategy
As with reality and previous subsims, attack at night when possible.

Always avoid destroyers and escorts. No, REALLY avoid them. Most DDs in SH2 are very difficult to evade and they can kill you on the first pass.
Torpedoes
Forget the one ship/one torpedo practice you were used to in Aces. If you have high realism options (dud torpedoes, limited visibility), you will need to fire a two torpedo spread for each target. Sure, you won't realize the 100,000 ton patrols you had in Aces but this is more in line with the pressures the real U-boat crews felt when deciding when to allocate torpedoes for targets.
AA guns and Deck gun
Use the , key (comma key) to switch between guns while one is reloading.

When trying to target approaching aircraft, let them come within range before shooting. We've had the best luck at ~1500m.

Go to flank speed when being attacked by planes on the surface.

Torpedo bombers will attack from steep angles.

Use the Z key to toggle on high magnification while gunning.
Evasion
The #1 rule of survival in SH2 is do not get within sonar range of British DDs in shallow water (>50m). You will die, be dead, that's spelled D-E-A-D. Unlike previous diesel subsims, the AI DDs will get a good fix on a U-boat in shallow water and with less vertical range to choose from, they can set their depth charges very effectively.

If you are cruising on the surface at greater than 64 time compression and you see it drop to 4x, that means your lookouts have spotted a glint in the sky, which will very soon be an "aircraft spotted!" Take this extra time to dive as deep as you can.

If escorts do detect you and attack, go as deep as you dare. The red zone on the depth gauge indicate below test depth. Ease you way into the red but don't venture too far or you'll be crushed instantly. It's a challenge knowing how deep to go.

Like real engines, if you push an SHII U-boat at flank speed too long, the Chief will warn you to reduce speed. If you are in desperate need of speed, simply drop to full and then ring up flank again. The momentary relief on the bearings will work magic (actually, the program probably times it but we like to use our imagination when working a cheat. )
Orders
As you might assume, Crash Dive (C key) will get you down faster than setting a subsurface depth or pressing P key (periscope depth).

Blowing ballast uses a great deal of your compressed air. Be careful when using time compression, it appears to use more air than at normal time compression.
Interface
In the map screen, press the space bar and right click the mouse to instantly center the map on the mouse cursor.

Use the CTRL-UP ARROW and CTRL-DOWN ARROW zoom in and out while in the external view. *Rainman

Miscellaneous
Before starting a campaign, be sure you are satisfied with the realism settings. Once you begin the game, you cannot alter the setting through the normal Configuration menu.

SH2 escorts have a depth charge accuracy level that exceeds what you are used to with AOD and SH1. When they find you on sonar, they will come right over and drop on you. Using the 3D screen, you can see exactly how deadly their targeting is. To compensate for this, we suggest turning the vulnerability realism setting down a few notches, ~70%. This will allow you to survive a few direct hits, in effect, rendering the accuracy factor less potent.
Mission Strategies


In the Blitzkrieg mission, after hitting objective point #1, you'll make contact with a northbound convoy. It's best to let them by, the DDs guarding them are nearly unbeatable. Simply stay away and then work your way south for objective point #2. Easier pickings are ahead.
