Just some Doom2 levels and an unfinished Duke3d map (think it became too big to be loaded) I was working on back in '96 '97!
Fortress.zip was a king of the castle type Death match arena for Doom2.
These levels had no enemies added but was built for mostly the architecture:
Level1.wad
Level2.wad
Level3b.wad
Level4.wad
Level5.wad
Shadow.wad
Spiff.map Duke3d Map that was quite intricate I believe but had an issue in the last room which caused it not to load in game ...
