To access the Titanic level "GOING DOWN" find all the time machine
pieces before you get to "THE RACK" and a second exit portal should appear
in the room just off the first.
To access the "WETWORLD" level play through level 3 'NUCLEAR WINTER'
and when you reach the rail tracks leading to the communicator you have
to power up drop off onto the roof below where you will see a medi kit.
Now jump off this roof into the water (which is only on 1 side) and swim
to a floating platform where you will see the level exit.
