Duke Nukem 3D
EDuke (Enhanced Duke Nukem 3D): created by Matthew Saettler was given away as a patch for Atomic Edition users on July 28, 2000. On this version 3D Realms removed the copyrights from the software so that players could do anything they liked with it and included a demo mod made by several beta testers. The demo included new Sector-Based Effects, Sprite-Based Elevators, Ladders, a Bouncing Particle Fountain, a Personal Teleporter, and a Sophisticated Translucent Water Effect. Saettler has kept records of his original Eduke site hee for reference.
