Secrets
This level has three (3) secrets:
 * 1) In the room below the one in which you start the level, to the right of the door through which you enter from the lake shore, there is a pipe that comes in from outside and goes up.  Jump over the horizontal part to find an Adrenaline and receive the message "You have found a secret".
 * 2) During the full exploration of the level, when you swim through the long underwater tunnel you receive the message "You found a secret area!" when you get to the other end.
 * 3) In the secret area, the circular structure around which the Tank is walking turns out to be a matter transporter that will take you to a secret level, the Comm Satellite.  Go around the back to use it.  On completing that level, you will be returned to the same place.
