One of the things absent from
Left 4 Dead was a lobby browser so you can choose servers easily. Before that you were at the mercy of what Valve's servers gave you. Now you can choose your own with the
latest update. I say it's about time as I thought that would be one of the things in the game at launch since games such as
Team Fortress 2 had it. Anyways, there are some more fixes so the next time you boot up
Left 4 Dead you'll be presented with some new menu options and the fixes.
