These CON files have been collected from all over the internet. You can find the link to all the pages used in the links section. To use a CON file, you must replace the CON files in your DUKE3D folder with the modified ones. Those files I think are user.con, game.con, and another one. Then you should run Duke3D as normal, and hopefully, you'll get the expected changes.

ENJOY DUKING!
