This page hosts 2 different Astrostein mods, both with 2 different versions.
Astrostein: Spifferaneous Edition
Originally released by Spifferaneous in the late 90's as a PC response to the Mac-only mod Astrostein. This includes 60 levels, plus updated graphics from the original Mac scenario. Choose from either PC style enemies or Mac style enemies
Astrostein: Original Laz Rojas version
This is a conversion of the original 30 level scenario by Laz Rojas for the Mac version of Wolfenstein 3D. Aside from packaging this up for easy use, this also adds the missing sounds that needed to be manually injected into the Wolf3D application. Also, for the first time, PC users can enjoy this mod, using the base files from the MS-DOS version of Wolfenstein 3D.
Both of these mods require the latest development version of ECWolf, due to using many features from the Mac version of Wolfenstein 3D.
Congrats on the launch, I added a download link to your article - hope you dont mind!
