Half Life 2 Coop players join now.

We are a group of half life 2 players who play half life 2 on coop. We usually play over coop servers on HL2DM, synergy, or obsidian conflict mod. If you're in need of a private room to play in, a buddy to play with, some coop fun, or maps that are not usually played much, then this is the group for you. I can also host listen servers if you want to play over those instead of going on the dedicated servers for those who do not want to play dedicated or want to play privately with a friend. You can also create your own listen server and have the group play with you. JOIN US TODAY!!

To make your own listen server...

1) open ports 4380 and ports 27000 to 27050.
2) create a server from the main menu
3) open up the console and type in sv_lan 0 and net start (your game should freeze a bit which is normal)
4) Restart the game
5) Invite people in

If it doesn't work then I don't know so you should post it somewhere.

A useful site for HL2 listen servers...
