Server admins, you can take the first step to getting your servers ready for the Team Fortress 2 madness on Monday.
First off, in preparation for the upcoming dedicated server for TeamThis news comes courtesy of Jason Ruymen on the HLDS mailing list.
Fortress 2, we've updated the hldsupdatetool. Along with that, we've
made the content for Team Fortress 2 that you'll need for a dedicated
server available. To get that, run hldsupdatetool with the command
"-command update -game tf".
The dedicated server itself is not yet ready. We're working very hard
to make it available as soon as possible. The Linux build might be a
little later than the Win32 build, but hopefully not by much. So for
now, sync up the TF 2 content that's available to get your server ready.
