Battlefield 2142

[gooface]

I have a question, I'm not sure where this would go but i was wondering if anyone knew how to make it so your computers by editing some file ( I know you can do it with quake 4) to make it so battlefield 2142 can not detect the internet so i can use offline accounts. now i know you can do this, and i have the DVD's and a legal cd key's i just don't want to have to make individual accounts and log in online on all of the pc's i play on i just want to make it so i can use a offline account and play in my lan, like you can do with the SP cracks for this game, without having the cracks. if anyone knows what i speak of and knows how to do this, please reply, and move my post if this isn't the right place to post this. thanks.
