We've added all kinds of new renderers, tons of cool features and upgrades for regular players, and thousands of additional editing capabilities and scripting extensions for mod creators. EDuke32 is completely free, open source software.
First brewed in August 2004 by Duke community leader Richard "TerminX" Gobeille—joined in 2005 by NVIDIA software engineer Pierre-Loup "Plagman" Griffais—and incorporating work by 3D Realms/Ken Silverman/Jonathon Fowler/Matt Saettler, what started as a learning experience and an excuse to learn C soon rose from obscurity to become pretty much the best Duke Nukem 3D port ever. We think you'll agree.
EDuke32 screams bad-ass so loud, you'll think Iron Maiden frontman Bruce Dickinson got uppercut in the balls by Freddy Krueger. We acknowledge that that is possibly the most ridiculous statement ever made, by us or anyone else—and we don't care!
You even get Mapster32, a hacked up and enhanced version of that good ol' BUILD editor you remember fruitlessly trying to make maps with way back in college—when you were sober enough to see the monitor, that is. Yee-haw!
