I'm new to L4D addons so I have no clue what to do here...
I want to be able to play L4D2 addons in single player mode. My college campus does not allow you to connect to Steam via their wifi, so I have to play offline.
I put the .vpk in the /addons directory, and enabled it under the "extras" menu ingame. When I go to launch a single player campaign with the custom campaign selected, I press "start game" and nothing happens. The game doesn't freeze or anything... just nothing happens.
Anyway I can load custom campaigns into single player, and play with bots?
