This map is very well done. The layout is well thought, the weapons/ammo/items are carefully placed. I really like it. Like TheMuffinMan say in his review this is a professional work. Also, it's pretty big and yes it may be confusing for moving in it at first but after a couple of minutes it's easier to find our way. My only disapointment with this map is that it doesn't support one flag CTF and Team Arena.
If you are interested, I've loaded the map on my Quake 3 public server @ 126.96.36.199 It's running the Threewave mod, you'll find the map in one of the voting room on the first floor. Sadly the level shot won't work in it - look for the blank level shot with the map name of desctf1.
