Guide:

After the planes drop you in the ocean you must either knock the other guy off his watercycle or press the ESCAPE button. When the real game starts you are an amphibious vehicle. Your screen shows the land immediately in front of you (you only go forwards). Fire the joystick to destroy rock formations.

By pressing the RETURN key, you bring up a view of the entire playing area. The white bases are friendly - do not destroy them. They will refuel your engines and guns. The small red things are enemy patrols. Simply use the joystick to move the cursor over one of these, and press the fire button. You will then move towards that enemy or base. Shoot all rock formations in your way or steer clear. If you go too far, your energy will run out and the game ends.

When reaching an enemy patrol, the game will automatically ALERT and send you underwater. Simply shoot the mechanical robots while avoiding their bombs. When you are all done, you will come back to the ship automatically. Sometimes you will have to knife fight a guy. Both arcade sequences are easily mastered. In the knife fight sequence there is a robotic device which can be knifed to the bottom of the ocean floor but its purpose is unknown.

The two bars to the right of the screen are fuel and gun power reserves. The rightmost is firepower, the leftmost is fuel. You can press F7 key to auto ALERT. Note: make sure your room is dark to see all of the detailed graphics.
