I setup a private Left 4 Dead server for us to play on.  

To connect to it either:

- Use the server browser- http://left4dead-servers.com/

- From the console type &quot;connect 69.65.59.229:27015&quot;

- Follow a friend

{dFb} Let's Shoot Shit L4D Server
69.65.59.229:27015
Password: dfbrocks

It's a private co-op server.

For those of you that don't know what Left 4 Dead is:
