Die Hard Nakatomi Plaza started originally as a duke nukem 3d total conversion but then they moved to half life goldsrc engine, the team even visited the fox building, but fox send them a cease and desist letter and the mod was cancelled

However the mod group created Piranha Games studio and sent demos for fox to convice to release the game, and then fox approved the development of the game which was released in 2002.

Searching for info of the duke nukem 3d version, ive found a link with a demo.

Thanks to darkcaleb forum duke4.net forums for proving a link to download
