Thanks to the unique development of Duke Nukem Forever, many oddities and oversights are present in the game.

Barcode on General Graves' Face
General Graves has a (rather smudgy) bar code under his right eye. This detail appears to be left over from earlier builds of the game, where members of the EDF had bar codes on their faces. This idea was abandoned at some point, but Graves' texture doesn't seem to have been updated to account for this change.

Mark Skelton's Duke Design
An older design of Duke by artist Mark Skelton was used by the game from C. the mid-2000s up until Gearbox replaced it with a model of their own at some point. Despite this, many assets seen in the final game still use renders of or are based on this older design.
Instances of this include:
- The cover of Duke's Why I'm so Great book
- Many assets from the Duke Burger level (both in multiplayer and singleplayer).
- The interactable statute used in the puzzle in The Lady Killer: Part 3.
- Kill icon of Jetpack going haywire (kill_jetpack.dds).

Drivable Trucks
The trucks seen in the "Highway Battle: Part 2" level can in fact be driven. This can only occur if a player skips to the highway with the Holoduke via a glitch or uses console commands.
Not only can the trucks with barrel-throwing Pigcops be driven, but a truck transporting a house can as well.

Direct3D Support Source Code
Found in System/Shaders/PC is FixedEmuTypes.h, which features some source code for support of Direct3D, specify Direct3D 9. The final game requires DirectX.
Why this is here is not certain, but it's likely a leftover from a build circa 2003.
