Duke Nukem 3D Hints

Where's the red card?

  • 1 of 5: The red card will open the door to the exit by the police car.
  • 2 of 5: First, find the hidden lift (activated by the blue key card) and go up into the factory.
  • 3 of 5: Maneuver your way through the conveyor belts, which is not hard, to the main room.
  • 4 of 5: Find the switches on the wall that open up another area (there is one on each side).
  • 5 of 5: The red card is lying by one of the monitors.
