This is a sort of remaster of my classic crap TsotsoFX. It's still crap but less so. I have fixed texture alignment at places, added new sky and music and map names, teleports to backtrack or save your from inescepable pits, new details and rooms added at least in few of the original maps, cleaned up sound effects to remove the very obnoxious ones, and more. Few of the maps might work on vanilla, but I got a bug and a visplane error on E1M7, but this is playable in modern boom compatible ports at least.
