WWII GI
A video game based on the Duke Nukem 3D source code and published by GT Interactive, WWII GI was the last commercial Build Engine game. It was programmed by Matt Saettler, who modified the con language to include variables and events. These CON language additions formed the basis for the original EDuke.
Although WWII GI was a fairly unknown game as well as commercial flop, due to the new CON code enhancements, a small number of user made modifications were made for the game as well.
