It seems the only option for playing Left 4 Dead with my friends is to have all computers online, even though I bought the 4 pack from Valve. Is there anyway to plan a LAN game on Left 4 Dead 1?
It is possible. If you use srcds to set up a dedicated server and note the LAN IP of the computer hosting it, you can enable the developer console in-game (under Keyboard settings then advanced) press the ~ key (on foreign keyboards, it is usually whichever key is next to the 1 key) to open it and enter the command
connect <LAN IP of server> into it. You'll then be dropped into the game. Make sure to edit the key of the server so that random people don't start joining. Consider setting it to LAN-only.
If you're using a non-QWERTY keyboard, sometimes binding the developer console may not work. If so, you can edit the launch options and add
--console. Then, whenever you launch the game, you'll have console open.
All clients have to be connected to the internet throughout, though. Steam DRM still applies. Mar 13, 2011 at 13:23
1@Bora Nope. You can run Steam in offline mode, and play it on a LAN. I've done it before.– user56Mar 13, 2011 at 13:39
Ok, scratch the throughout part. You have to connect to Steam once to switch to offline, at least. Mar 13, 2011 at 19:16
1@Bora Also not true. If you reboot your computer without a working internet connection, Steam offers you the option to switch to offline, assuming you have logged in some time before that.– user56Mar 13, 2011 at 23:37
I was referring to the "some time before that" part, which might render the whole process inconvenient, just for the sake of getting around the DRM process. Mar 13, 2011 at 23:58
