CTF-Space Station 03
This is an original map for Ace's version 1.0 CTF mod, by Jay Williams - who has also adapted Face Remix for CTF. While the limitations of this first version of the mod mean that the bots can't actually capture the flag themselves, they can indulge in some regular team pointblast behaviour, and make your flag-capturing none too easy. Online, of course, playing "multiplayer" against fellow Nabbers, there should be no problem, though I don't promise you will always respawn at the correct end!
The map is none too large, but it seems sensibly designed for CTF, with multiple routes between flags. As the first fully original NAB CTF map to be released, it seems a pretty good effort to me!
