er.. I have some bad news though. Both bioshock 2 and bad company2 do not support LAN. Bad company 2 hasn't made it official yet. They have released info of a scheme to allow users to rent servers from the developers( DICE). This however will mean that an internet connection would be needed to get on to these dedicated servers. The extent of the connection isn't known yet, but bioshock 2 doesnt support LAN for sure. If that wasn't enough- starcraft 2 has also been confirmed without LAN support. It looks like all our favourites are going the same way MW2 ended up.
