Going on a trip to where's no internet connection, but still want to play your FM15 while there? This tutorial will show you how to play the game in offline mode.
Even thou this tutorial will show you how to play your FM15 in an offline mode, you still need to be connected to the internet before you can go on and play it offline.
Play FM15 in Offline Mode
Start Steam online - make sure the Remember my password box on the login window is checked
Verify that all game files are completely updated - you can see the update status for a game under the Library section (when the game shows as 100% - Ready it is ready to be played in Offline Mode)
Launch the game you would like to play offline to verify that there are no further updates to download - shut down the game and return to Steam once you have confirmed that the game can be played
Go to Steam > Settings to ensure the 'Don't save account credentials on this computer' option is not selected
From the main Steam window, go to the Steam menu and select Go Offline
Click Restart in Offline Mode to restart Steam in Offline Mode
Keep in mind that there will be updates for FM15 in the future, so every time and update is released you'll be required to go back online again, so that an update can be downloaded and properly installed on your machine.
This step is also optional, but it is preferred. Because with updates, developers try to resolve bugs and in-game issues that you might encounter in the game.
Also note, that you won’t be able to access Steam community while playing the game - via Shift + Tab keys.
