Ultimately, playing in Offline Mode is a roll of the dice whether your achievements will correctly track. If the call failed then either Steam is not initialized or you still havent processed the callback from the initial call to RequestStats. For example, if it requires connection to a server to track something, you won't earn the achievement. However, this depends on how the game has implemented achievements. All those achievements will show as unlocking at that time, rather than when you actually earned them. Ordinarily, the game still tracks the achievements you earn when offline, but only syncs them to the Steam server when you next go online. To disable Steam's Offline Mode, select Steam > Go Online from the top toolbar. To see Hidden Games, click on at the top. While the feature typically works without a hitch, it can sometimes cause achievements to not unlock. If the game you have purchased is not in your library, it might be added to the Hidden Games list of your Steam account. Steam's Offline Mode is a great way to play Steam games without an internet connection. My old computer has the same account as my new computer.
