Duke Nukem Forever Screenshots in Duke Nukem 3D

The Xbox LIVE Arcade version of Duke Nukem 3D, just released last weeks, appears to have some hidden screenshots of Duke Nukem Forever hidden within the game. These are unlocked by obtaining all 200 achievement points in the game. The YouTuber who uploaded this explains:

First image appears to be Duke reloading his pistol in front of an enemy Octabrain. From the backdrop of the level, it looks like some sort of dam. You can see another Octabrain in the background on the top left.

Second image is just Duke smirking with two scantily clad women in the background.

Now we just need an update, 3D Realms.
