Hidden levels

Sent in by Code Hunter



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.
