If you choose exit (without logging out) from systray icon, when you open up steam again, it should say something like, "steam network unavailable." choose continue with offline play, the only game you can start in this mode, so far, is dedicated server. Unfortunatly, I dont know how to run dedicated server and play all from the same computer in offline mode yet. You can try connecting to your offline HLDS on another (offline mode) computer on your LAN. Seems like this should work, but I don't have two computers to test it out... Someone try this and let me know!
