CTF4/CTFM seems very popular recently, I know of at least 2 forums that seem fixated on it recently. Contributed what I knew and I may be sending some map edits and other recommends regarding soon.
Thought I had of the 2 prefixes for the gametype a total of just under 50 files...
...turns out I have 52.
Additive: Just noticed more in that last screenshot that weren't highlighted. Whoops!
