Will be good if you consider install VCTF (Vehicle CTF) maps to server(s).

Info about XVehicles you can found here: https://ut99.org/viewtopic.php?f=34&t=14936

As I see, most fit server is --- Normal Weapons CTF (Grapple Hook) -- London ---, since hard expect users want play in VCTF when come to ComboGib server.

But I can be wrong and on ComboGib it can be too fun.

This maps must work as usual CTF maps, not need change game config. At least I hope for that.
One problem - if you use ACE, you need list packages in ACE config, as described here:
