The story so far....

A  group  of  terrorists  have stolen  some  of  the  most  modern 
submarines in the world. The terrorists want to use the submarines 
to  sink  your ships. It is your task to find these submarines and 
if possible destroy them, before they destroy your ships. To carry 
out this task you fly a LOCKHEED S-3A VIKING.

How to play the game:
  
After the game has loaded, the title screen appears.
While the music is playing press the spacebar to continue. You can 
then select the level of difficulty. Press the funtion keys to se-
lect a level and start the game. 

The game itself is fully mouse-controlled.  At the bottom left  of 
the  screen you see a couple of arrows.  Clicking on these  arrows 
with the left mouse button moves the plane on the map. 
The white vertical line on the map indicates the ' save area'.  To 
the left of this line there are no submarines. You can also refuel 
when you are to the left of this line (see below).

The M.A.D.
As  soon as you move your plane you will here a sound and  at  the 
top right of the screen a line appears on the green display.  This 
is the magnetic anomaly detector (M.A.D.).  The M.A.D.  is able to 
detect  small distortions of the earth's  magnetic  fields.  These 
distortions  are caused by submarines.  If the line on the  M.A.D. 
display is straight it means that  no distortions (no  submarines) 
are detected.  If however the line is distorted, a submarine is in 
the vicinity.  This means that the submarine is in a square above, 
below,  left  or right of the square your plane is in.  By  moving 
your  plane around while looking at the M.A.D.  and by using  your 
brain  a bit you can determine the exact square the  submarine  is 
in.
While you're moving around make sure you don't move on the  square 
where you think the submarine is in. If you do, your plane will be 
shot down by a missile launched from the submarine.

By clicking on 'M' in the middle of the direction arrows, with the 
left mouse button, you can toggle the M.A.D. on or off. Wether the 
M.A.D. is on or off is indicated with a light at the top middle of 
the screen.

The sonobuoys
When you think you've found the square the submarine is in,  it is 
time to drop a sonobuoy.  The sonobuoys are used to determine  the 
exact position of the submarine.
To  drop a sonobuoy click the RIGHT mousebutton.  A light  at  the 
bottom  right of the screen starts to flash (to turn it off  click 
the right button again).  On the bottom middle display you see the 
word sonobuoy appear. Next move your plane on the square where you 
think the submarine is in.
If  the submarine isn't in that specific square nothing  happens, 
although you loose the sonobuoy you've dropped.
If you've found the submarine however a voice shouts 'I got him, I 
got him' and  a couple of dots appear on the round display at  the 
bottom of the screen. You also get your sonobuoy back (look at the 
number at the bottom right of the screen).
Next come the depth charges.

The depth charges
After you have seen the enemy I.D. click one of the mouse buttons.
The  left  control panel scrolls down and the depth  charge  panel 
scrolls  up.  By  clicking on the left/right arrows on  the  depth 
charge  panel  you change the direction your plane is  flying  in. 
To drop a depth charge click on one of the F's. Before you do this 
however  you must adjust the depth at which the depth charge  must 
explode.  Click on the slider bar with the left button,  hold  the 
button down and move the mouse up or down.
On  the bottom centre display you see the number of hits  required 
to sink the sub and the time left before the sub disappears.

Enemy view
While  you're  trying  to find and  destroy  the  submarines,  the 
submarines  are  trying  to  destroy  your  ships.   At  irregular 
intervals the game switches to enemy view and you can watch one of 
your ships being sunk.

Refueling
When   you're plane's  moving around it consumes fuel  of  course. 
Look at the bottom middle display for the amount of fuel left.  To 
refuel  move your plane to the left of the vertical white line  on 
the map. The plane is then refueled.
To move your plane a bit faster you can toggle the M.A.D.  off and 
then move to the left of the vertical line via the squares  you've 
been before.

Game over    
The game is over when:

- all submarines have been found
- all your ships have been sunk
- you are out of planes
- you are out of sonobuoys
- you switch off your computer
