1) the .bat file with this:
openarena.exe +set dedicated 2 +set net_port "0000" +set fs_game CTF +set bot_nochat "1" +exec server.cfg
+set net_port "0000" doesn't sound good, you sure about this?
But We need the MOD not only the traditional server.
I tried to google
for it but found little worth
of interest. Your best bet is A) to google
yourself or B) ask RUD since he is running his servers with it. It does however seem like RCTF is something that belongs to UT.
