TDU2 Community, 

Thank you for making TDU2 a huge success worldwide. We’ve reached the top of the sales charts in many territories and continue to work diligently on making TDU2 the best persistent-world racing game on console and PC.

The first of our game optimizations for console will be live tonight on Xbox 360 at 1am PT (9am GMT) and PS3 is soon to follow. This update will resolve a corruption issue that some players experienced with their saved game files. In some cases corrupted files will be automatically repaired. 

Available on Monday, 3/14 at 1am PT (9am GMT) will be a patch that should address many of the outstanding concerns that some of the community experienced on PS3 and Xbox 360. We have worked diligently to stabilize the network and address log-in issues. Friends lists will now be populated, invites will work correctly and Clubs will be brought back online. The Casino has been optimized and the bug causing players to lose money has been resolved. We have also addressed many of the exploits in the game and will be monitoring cheating in all its forms.

The TDU2 community has been a great support to the development team and we look forward to rewarding your loyalty soon with free DLC content. We should be able to provide dates once Microsoft and Sony approve the content and will update the community as soon as they are expected to go live.

Best,

The TDU2 Development Team   

The clubs patch is late (today is a day after the original specified time), and may be released in an hour, according to what they have said on their Facebook .

Awesome, I'm gone most of the day but I look forward to checking it out this evening.
