I've got a basic L4D2 server up and running for us to play on.

Its locked down to only The Mighty members on Steam and should show up in the servers list bottom right when you load into the game.
If its not showing up in your Steam Group Servers the bring the console down and type the following to connect...

connect: 212.159.60.202:27050

The game type its set to is co-op, but can be voted on to change if you want.

Can those of you who own the game try and connect and let me know any issues so I can fix them.

Once I know its all working I will tweak the server.cfg so that we have more zombies and stuff to make it more interesting.

Sounds awesome!

After a test run it seems to have gone ok. Although locking it down to the Steam group didn;t seem to stop others joining it for some reason. So I've put a password on it muhahaha!

And also added a few extra fun plugins as well to spice the game up. It set on normal difficulty for the moment just to see how the plugins effect things.

Steam should spam an event out to you all with time and date details. :].
