This is a game I made 7 years ago, first Wolf3D mod. I re-wrote the engine to the Wolf4SDL 1.7. I went through all of the maps and fixed them up, but did not change them drastically.
Here's the source code. I felt it may help wolf3D modders see the clever things that have been done in here. Many were collaboration of the Wolf3D community...
Working on DOOM Legions Revisited, I found a few bugs in this game. The switches may not save correctly (not sure). Unfortunately, my fix may corrupt...
I fixed a few things in game, apply this to the existing 1.00, just a copy+paste.
Merry Christmas, and here is what you have been waiting for. I hope you enjoy. (EDIT: Version 1.02 here)
