Gmod Offline

I want to run gmod on my laptop but it does not have internet connection.
Is there any way i can get it to launch gmod offline ?

Any help is greatly appreciated.

Start Steam in Offline mode, start G-mod and then start Singleplayer.

Last time i tried that steam said: “cannot run this game in offline mode”

None of the steam games can run in offline mode.
I find it annoying when my internet goes out.

What do you mean? I run my Steam games offline when I don’t have connection. You just have to run Steam offline which should do it automatically if you were logged in at least once.

OH, a make sure that you have “don’t save account credentials…” unchecked in Settings.

You must first launch the game once in online mode, THEN switch to offline mode.
