I've been having a blast revisiting this game. I bought the game from GOG.com and upgraded it with EDuke32 • Duke3D for Windows, Linux and OS X . Than I installed the high resolution pack Duke Nukem 3D, Duke Nukem Forever and Duke plus from fissile materials Fissile Materials and some of his mods. With all the upgrades it doesn't seem like the same game. Has anyone tried this?
