I’ve been meaning to put up some Borderlands tweaking instructions all week, but I don’t think I could have done it better than this thread on the Gearbox forums. Thanks to Mr Berry for pointing that out to us. Crucially, one of the commands in there allows you disable the voice-comms for the game, so you can use something more sensible. We’ve had no word back from 2K/Gearbox on whether there will be a patch for that stuff, but I guess we’ll find out soon enough. If you are tweaking, don’t forget to back up the relevant files before you start editing, as there might be some problems with loss of keybinds and such. The other issue is port forwarding, the instructions for which are in this thread. If you’re having trouble hosting/connecting to co-op games then you probably need to get busy with that stuff. Sigh.
