Falcon's Rebellion Express is a mod for registered Wolfenstein, made by Emperorlord. It was finished in June 2000 but never posted nor mentioned at the Wolfenstein 3D Dome. Instead it was posted on Emperorlord's own site.
As the title screen indicates ever so slightly, the only new levels are on Episode 1. Levels are very large in size, and not that well made. Adolf Hitler can be found in level 3.
The mod is playable in SDL as no coding changes were featured.
