Ok, I've found a better quality video, but the problem is that you must download it, and it's quite huge (the zip file include two versions of the same video) so you must be patient.

I made some screenshots of some detail that I noticed:
The start of E1L1...
...the sky look like a dusk version of the usual night L.A. sky.
E1L2, entrance of the shop. Notice that the security camera is white instead of black.
Inside the cinema. The Sister Act poster is different, the art look bigger and the title is not the same, but I can't read what's written...
... but the Bleached Blonde poster is clearly visible, and the title say: "Debbie Does Duke"
Inside of the projection room. Thats me, or the font of the pickup messages is the same in Doom?

After cleaning up the show room. The portable medkit has a different logo on it. Notice also the barstool is gray instead of red.
Entering the arcade room. I did not notice immediately, but it look like a trooper is using the unused shooting animation:
I also found lots of scans of DN3D. They are perhaps not so interesting that I had found, but some screenshot are worth it:
Scans from Joystick N70: It's look like they used the V1.1 version (see scan below), but there are also some screens of the beta DN3D lying around...
Page 48(the official artwork

)
Page 49(some screens of DN3D...)
Page 50(there are a screen with a lizman using flamethrower)
Page 52(more screens. Also a screen with a Battlelord in a unknown level)
Page 53(Showing weapons. Including the flamethrower. Notice also the shrinker explosion sprite is rotated horizontally)
Page 54(more screens, featuring the amazing 'adult mode on/off')
Page 56(Interview with Greg Malone)
Page 57(more screens, and a screen of a Battlelord in the beta _zoo.map)
Page 58(a screen showing GAME.CON opened with EDIT.COM)
Page 60(Duke's evolution.)
Scans from Joystick N61: there are some interesting beta screens from Apogee:
Page 144(Ruins: return of the Gods)
Page 145(Beta Duke 3D)
Page 146(Xenophage and Shadow Warrior. The snake boss look impressive here)
Page 147(Terminal Velocity)
And finally, one last scan that intrigues me: It's a commercial with only two screen of beta DN3D. The first screen is either E1L1 or E1L2, but the second screen more intersting because we can see Duke carrying a different shotgun model...

Well I think that's all for today...
