Duke Nukem 3D Hints
Where is the red keycard? Where do I use it?
1 of 5: Most is this level is based around one central room. It is very large and shaped like a ring. That is the "large room." It is the room just past the passage with the red lights. In the "large room," look for a small hole in the outer wall with green slime around it.
2 of 5: Follow this path down a treadmill all the way to the end.
3 of 5: Be prepared for a big fight!
4 of 5: The red keycard is on the control panel.
5 of 5: Use the keycard to extend the ramp in the large room.
