Secrets
Secret 1: Top of the small pyramid

In the fire room with the lava, destroy the crack in the wall and walk through.
Secret 5: Crack in the water room
In the water room, find the crack in the wall and walk through.

Walkthrough
Easter eggs
- Serious Sam can be found in a secret area of the desert beside the smaller pyramid. Duke quips, "Why so serious, Sam?" (see the following Trivia section).
- The four "element" stones that Duke must activate inside the pyramid are a reference to the movie The Fifth Element.
- The final spaceship has some exterior/outer zones with pyramid shapes. This maybe a reference to the pyramid-shaped spaceships seen in the movie Stargate and its subsequent TV show Stargate SG-1.
Trivia
- Serious Sam's cameo appearance on this level may be an attempt by the Duke Nukem developers to make a friendly jab back at the developers of the Serious Sam franchise for featuring a deceased Duke Nukem in Serious Sam 2.
