I was looking for this map ever since I first got aleph one working. I like the cramped hallways, and it offers decent defence for the flag (finally) with the need-to-go to teleporters, unless you use the switch, and the "secret" door behind the flag. It is my ideal map, but I am known for my weird tastes. I still remember JC's reaction when I first hosted it: "ewwwwwwww"
That email winky is for me. ; ) right back atcha.
This modifcation of Dave Baily's map is my first attempt at CTF. For some reason some people like it though personally I'd choose CCR2 (part of Magenta Filter 1.3) This version works with CTF lua 4.0.2 so you guys can stop bugging me to email you maps. ;) The readme goes in to further detail.
