Duke!ZONE for Duke Nukem 3D

I completed a video showing off most of the 500 maps, they were three that wouldn't work but the rest seem to work to some extent.

If you type in Duke3d (DukeZone 500 maps catalogue)

Duke!ZONE is not a expansion pack, just a shovelware multi-player/duke-match map pack for Duke Nukem 3D both 150 levels pack and 500 levels pack are godawful, half of the maps are broken and some you have to cheats or no-clip mode to progress, despite theres no map end. this is clearly made people who never used editor tools before, because this is 1st grade level of mistakes here. STAY AWAY!!! from this garbage unless you have a friends whos willing to play and suffer with you, at least you have some minor fun out of it. also stay away from "Duke Assualt" another garbage Map Pack. "Duke!Zone II" on the other hand is a much better expansion, yes it still has the garbage multi-player maps from duke!zone, but get this, it has actual 3 episodes single-player levels, and the levels themselves are not that bad.

From Wikipedia:
"Duke!ZONE: An authorized add-on released in 1996, published by WizardWorks, which includes 500 fan-made levels and various editing utilities."
