What better way to meet a new friend than a headshot?

1) First start the game you wish to play (ie: Counter-Strike: Condition Zero).
2) Click "FIND SERVERS" (or similar option).
3a) If you're trying to find a LAN Multiplayer Game, click "LAN" > "REFRESH", and double-click on the game you want to join.
3b) If you're trying to find an INTERNET Multiplayer Game, click "INTERNET" > "QUICK REFRESH" or "REFRESH ALL", and double-click on the game you want to join.
3c) If you're trying to find a specific or saved FAVORITE Multiplayer Game (like "Chokaay's CZ Wedding Bash" above), click "FAVORITES" > "ADD A SERVER...", type in the IP Address, and double-click on the game you want to join (if it appears).
3d) If you're trying to find a specific server your friend is currently playing on, click "FRIENDS" > "REFRESH", and double-click on the game you want to join (if it appears).
4) If the server you're trying to join requires a password, type in the correct password when prompted.

NOTE: Option "3d" may NOT always work if the server your friend is playing on is behind a router and uses a localized IP Address (192.168.0.XXX). You may need to ask your friend for the server's public IP address and use method "3c" to join the server, if this is the case.
