Um...
K, the demo servers should be up and running and associated with the steam group. I can't really check if they're working because I don't have the demo installed anymore.
Full game will be unlocking in 4 hours from now anyway.
I will update the dedicated servers from "demo" to "full game" hopefully right away at 10pm. There might be a delay, because I assume steam will be assraped for an hour or so (happens around big releases) so depending on our luck, the servers might actually not update to "full" for some time.
I'll be on vent for sure, so ask me if you have any questions.
INSTRUCTIONS AS TO HOW TO GET ON THE SERVERS (when everything is up):
OK, this is assuming everything is the same as L4D. L4D2 is not out yet, so I can't test if this works, but it should. If it doesn't, I'll try to update the instructions.
Basically what you do is:
Option 1: Connect to the TBG servers straight from the steam group. Assuming that you're in the TBG Steam group (if you're not, search for it and join it - it's public), they should be showing right on the main menu or wherever they put the "steam group servers." This is easiest, but also lamest, because once everyone is in you have to restart the campaign - it's a "direct connect" without lobby.
Option 2:
1 - Enable "developer console" somewhere in options. I think it's in "keyboard" options oddly enough in L4D. It should be somewhere in options in L4D2 too.
2 - Open the console and, as lobby leader paste this in your console and press enter:
mm_dedicated_force_servers 64.34.213.182:27015
OR
mm_dedicated_force_servers 64.34.213.183:27015
We have two servers up right now, both can run whatever gamemode is forced on them from the lobby.
After one of the two above is pasted in console, as a lobby leader when you press "start game" or whatever, the corresponding TBG server will be found and used first (if it's not full).
There's a way to automate that command so it's executed every time you launch left 4 dead 2 (with autoexec.cfg) so you don't have to type it every time. Ask me how if you want to.
Easiest for tonight will probably be to go straight in the server and invite with the friend list, then restart the campaign once everyone is in (assuming campaign mode). For versus, you pretty much have to do the command.
Let me know if you have Qs.
P.S. BTW the servers are set right now to only be steam group exclusive, which means that no pub games will go on them. Once you start a game from a "public" lobby, pubs can still join in-game though, if someone (rage) quits. I'm not sure if pubs can join if you go straight to the server from the "steam group" interface in-game, because I never connect that way - I always connect with the mm_force command using a lobby.
P.P.S. It might be possible to only enter one command instead of two for the left4dead2 servers (in which case it uses the first (leftmost) non-full server). Theoretically it should look like this:
mm_dedicated_force_servers 64.34.213.182:27015,64.34.213.183:27015
HOWEVER, I have not tested the above command with multiple IPs, and I'm not sure if it will actually work...
