I'm late to the party for sure, but here are all of my maps

I worked on the port of Quake 3 Fortress to Wolfenstein: Enemy Territory in 2005 so I was the curator/porter of all of the Quake 3 Fortress .map source files which got modified into TF2 versions by myself. Fun fact: the Q3F dev team turned into
Splash Damage. Q3F was a very fun version of TF, way way faster than TF2 which is why some of the maps here might be stretches. When that dev team made Wolfenstein: Enemy Territory, also run on the Q3 engine, they allowed Q3F to be ported to ETF.
The ones I ported to TF2 were relatively "good fits", or OK ones... AT THE TIME. I haven't played TF2 in years so who knows how they hold up... near as I can tell people don't run old custom maps much. Lots of heavy modifications through and through, the old TF games were much faster and in a lot of ways much better (a point of contention of course
Ports
Duel - QWTF original / Q3F
Impact - QWTF original / Q3F (Q3F .map file base)... I believe the only decompile.
Stag - Q3F original (ETF .map file base)
Mach - QWTF orgiinal / Q3F (ETF .map file base)
Chaos - Q3F original (ETF .map file base)
Canalzone - QWTF original (NOT TFC, TFC is garbage) / Q3F (ETF .map file base)
