We now have two L4D servers. 69.90.34.217:27015 69.90.34.217:27016 Alternatively, when you launch L4D, they'll appear under your steam group servers (assuming you're in BBRP community)
Whats differnt from going to a dedicated server provided by the game, or going to a server controlled by BB?
The game doesnt provide dedicated servers, you connect to a dedicated server that someone is hosting. It's just part of the matchmaking system. With the [BB] ones you can instantly view and connect to them. It's possible to make it so it's for the group only.
