Since the launch of the new Uplay PC, we've been carefully reading all your feedback, and we think some clarification is required regarding offline and online modes.
When running the new Uplay PC client while being connected to the Internet, you can benefit from all the functionalities and services it offers - such as the friends system, actions & rewards, latest news and more - and of course enjoy the online features of your games. However, you are not required to be online at all time to access your games.
As long as you've already logged in successfully once, the client is designed to switch automatically to offline mode if you don't have an active Internet connection or cannot connect to the game servers. Also, if you wish to force the client to start directly in offline mode, you can tick the "Always start in Offline Mode" box in the Settings, either directly from the login screen or the small cog in the menu bar.
When in offline mode, most features will be unavailable, but you can start your game from the Games tab as usual. All games in our current catalog can be played offline after they have been activated, with the exception of Hawx 2 and Settlers 7, and your solo campaign will resume from the latest local save. As a note, if you play on a single computer and don't have the need for Cloud Save Synchronization, you can also disable the option in the Settings.
If you have any question regarding Uplay, you can contact us on the forums, on twitter.com/uplayubisoft or on facebook.com/uplay.ubisoft. For support requests, make sure you fill a ticket on http://support.ubi.com.
