Server Files
Renting Servers
Dont matter, other recent games like MW3 - its not much you can do to change the config files. BF3 for instance, you cant do anything but for a few changes using a control panel, restricted by the same company - even the game provider is restricted and only a few are approved. Overall, wont be much different from the original BO (server side).
MOD Tools
Might be available later once the game is more mature.
