This level is set on a large military ship in the middle of the sea. It is one of the biggest levels in the game, almost equaling Dark Side (Not Smithsonian Terror however). This mission will take you a while and will chuck everything at you. Warning! You may get lost...
There are 5 secrets in this level.
Secret #1: Diving in
This secret can be visited before going aboard the ship. To find it, dive underwater and swim under the boat. You should notice a little hole in its hull, marked with yellow and black stripes. Swim to it and emerge from underwater there. You will have to face 1-2 alien beasts. Then simply walk in the small corridor and collect night vision googles, armor, chaingun cannon and steroids.
Secret #2: Playing in the kitchen
Inside the dining room/kitchen of the ship, walk towards the small part with ooze cans. There you should notice some cupboards covered in blood and bodyparts. On one of those cupboards, with a head and a knife on it, there is a switch. Flip it and a small room with a portable medkit will open on your left.
Secret #3: Duke is on TV
Inside the barracks on the ship, there is a room with some assault troopers as well as a couch and burning TV. Simply jump on the TV and that is where the secret is located. Behind the TV there is chaingun cannon. Aside from that, a small place will open in the opposing corner of the room where a shotgun is located.
Secret #4: Nasty captain
This secret is located in the captain's room, where the red keycard is located. Just above the desktop where the keycard is, there is a clock. Press use/open in front of it and the bookcase behind you will go down as well as the wall behind the bookcase will open. There is a secret room with shrinker, 2 ammos for expander, 2 atomic healths and some of the captain's nastier toys.
Secret #5: Boxes and cranes
Behind the yellow keycard forcefield, locate the room with 1-2 assault commanders and a giant stack of boxes. There should also be a crane operating them as well as conveyor belt. After dealing with the enemies, climb up the boxes. Another assault commander should emerge from between them - kill him and jump to the space behind boxes where he was waiting for you. Now turn towards the wooden boxes without metal frames on them - there seems to be one box missing under a bigger one. Walk in that place and collect the RPG and protective boots.
- The name of the ship - Valdeez-2 - and the captain's room, with the bed and the liquor bottles strewn about, seems to be a reference to the real-life Exxon Valdez oil tanker, which ran aground in 1989 because its captain had fallen asleep due to excess drinking.
