Hello everyone.

Good news. That thing the other day worried me.

very good news

I had forgotten that I read this same thing a month ago... lol

Thanks Luke for putting these "rumors" to rest. I would'nt put it past competitors spreading this to counter their own mistakes (i.e. COD MW2).

Well it's not like the dedicated servers we host right now. With CoD you can mod the game and a lot more than what you can do with BF servers. But really all we need as far as a dedicated server goes, is the ability to kick people. Then we can put our own rules in place and enforce them.

Awesome....

Orck BF BC2 dose come with MOD tools and you can edit a lot of options just like COD. When you load into a server take a look at the server settings that pop up.
