Schabbs 3000 is a mod for registered Wolfenstein, made by Ling Yan Li. It was released on June 19, 2005.
The mod is based on Gary Ragland's Schabbs 2000 with many levels being lifted from that particular mod. Barry Christian's Armageddon plays a role as well, with the latter part of the mod drifting in that direction.
Many new wall textures are included; 149 in total (this includes doors and elevator switches). Many new objects and extra bosses were included as well. Other coding changes include new ceiling colors, new music order, seamless level flow and four keys.
Six years later, a revised version was released.
