Well what is it .torrent for?
I also noticed that with HaloCE when you open a server and edit a gametype in CTF it says <string needed> and when you set the ammount of captures to win to 10 you only need 3 captures to win
I think you don't understand. .torrent files are files you've to download with a program, in this case, bittorrent. It's just like eDonkey, eMule but in a slightly different way.
That torrent files you speak of, is the same file as the normal downloadable file, you only need a client (program) to download it...
But why do you ask, because most server which host the file are down or full, torrent files are always available, so when you can't connect to a normal server to download, let's say the HEK or HaloCE, you can just download it using bittorrent...
