Offline Mode allows you to play games through Steam without having an active connection to the Steam Network. This feature is useful when you have limited or no internet access.
Firewall settings may prevent the Steam client from updating. Please see the Troubleshooting Network Connectivity FAQ for further instructions.
Most games require an initial start-up while connected to the Steam Network before they will work in offline mode. If your game's status is "100% - Ready", but you receive the message "This game cannot be started in Offline Mode" when attempting to play offline, the Steam client and/or game files need to be updated.
Games that require an active connection or use an external launcher will not work in offline mode.
