The old developers were 3D Realms, but they're no more I think. Now the projects gone on to someone who knows how to finish what they start, but of course since I played the earlier Duke Nukems and had a blast with Duke Nukem 3D, I would've liked to see 3D Realms put that game out .. But they had their chance over and over again, so.
I remember I saw this in the late 90s and my mind was blown
Everytime I've seen game footage, I've gotten the impression a lot of the game was basically done.
