- In the first level of the fourth episode, when entering the "Briefing Room", the player can find a "Steed" umbrella and hat hanging on a wall. This is a reference to the character John Steed from an old British show The Avengers.
- In the beginning of Episode 4 Level 5, the player will come up to a board with wanted posters. These are actual pictures of the developers of the game.
- The fourth level of the fourth episode, Babe Land, is entirely based off of Disneyland.
- In the level "It's Impossible", at one point you will pass a large sequence of doors that will open as you walk through them ending with a telephone booth at the end of the hallway. This is a reference to the opening title sequence of the 60's spy comedy Get Smart.
- Near the end of Episode 4 Level 1 you will find a telephone with U.N.C.L.E. written on it. This is a reference to the 60's spy show The Man from U.N.C.L.E..
- In the level Duke Burger once you reach a sign with Duke's head and use the "Order here" part of the sign, a recording will start to play, saying "Go away, we're closed.". This is a reference to the show Beavis & Butthead.
- In Episode 4, Level 5, at one point in the beginning the player will get into a small office area where he will find a policeman's desk, specifically H. Callahan's. This is a reference to Dirty Harry.
- In Episode 4 Level 5, after finding the yellow key, the player can end up in another area with a policeman's desk. That one contains the desk of J. McClain. After revealing it, Duke will prompt a line borrowed from the original Die Hard movie.
- In the same room with the Die Hard reference, a picture parody of the Unabomber can be found.
- In Episode 4, Level 5, in the room with the entrance to the secret level, the player can find a gag to Judge Dredd.
- The UFO in the secret level of Episode 4 looks similar to the alien ships from The Independence Day.
- In the secret level of Episode 4, in the hallway with a puzzle, there is a picture which is yet another reference to The Independence Day.
- The exterior of the post office in the level Going Postal is modelled after a real life post office that houses the PO Boxes that 3D Realms have had for over 20 years.
- In the level Going Postal, there is a reference to The Simpsons, particularly to a 1993 episode titled "Brother from the Same Planet". Near the bathroom there is a message written next to it, which reads "Trab pu kcip!", which when read backwards is "Pick up Bart!".
- One of the secrets in the level Going Postal contains an area called the "Postal Rifle Association". This is a play on the actual "National Rifle Association".
- In the level Critical Mass, at one point the player would have to go through a grate, just to fall into a trash compactor with water in it. This is reminiscent of a similar scene from the original Star Wars movie.
- In the level Critical Mass, one of the secrets contains a room called SECTOR 7-G. The room also contains boxes of donuts. This is a reference to The Simpsons: Homer Simpson is known to eat donuts at work, and the part of the plant he works in is called "Sector 7G".
- Near the end of the third level of the fourth episode the player can find a secret area. In the middle of the room there is a post with Snake Plissken on it (Kurt Russell's character from the 1996 movie Escape from L.A.). Upon revealing him, Duke will prompt "I guess he didn't escape from L.A.".
