SUBMARINE MANUAL,script made by madmax and modified by bunga dunga 
------------------------------------------------------------------------------------------------------
VERY IMPORTANT - For this to work, you need to be on 
RUNNING mode. REMEMBER................

MOVEMENT BASICS
1. The submarine is available in seyda neen.
2. buy a key from the trader for the submarine to start.

4. Once inside, use RUN to increase speed and BACK to 
    decrease speed.
5. To turn right and left, use STRAFE RIGHT and LEFT.
6. You can toggle the control modes by activating on the 
    submarine. There are 2 main controls, SPEED and LEVITATION.[spacebar]
    The SPEED mode will enable the above control operation. In 
    LEVITATION mode, RUN will levitate up and BACK will levitate 
    down.

U CAN BUY A SUB AROUND SEYDA NEEN

also for getting in and out of the sub. it will have some magic to use,there is also a room for your stuff[magic use also]

OTHER FACTS
1. Maximum speed is 15.[to fast and it crash the game,15 is ok]
2. You can rotate around freely during sailing or stationary mode.
3. Best view in first person perspective ( cannot change view ).
4. The submarine cannot be damaged.
5. It can only go up to a height of -100. Which is just enough for
    you to view the surface ( a bit like the telescope ).
6. For v2.0, , creatures/fishes will not attack you. ( 100% chameleon )
7. Collision detection is using one NPC at the front. So don't be
    surprise if you see a shadow casted on the seabed.
8. The NPC carries a light which helps to illuminate the
    surroundings for better visibility.
9. Same cell change issue as above. To get submarine back, just 
    trace back where you come from.
