One of the big additions to this year’s edition of Codemasters’ Formula One racer is the ability to take part in a racing season co-operatively with a friend online, which means that not only will you be sharing in the glory of victory together, but also competing with one another for points and car upgrades in the same team.

This Co-op Championship Mode in F1 2011 then gives players a glimpse at “the intense sporting and political rivalry that exists between drivers in Formula One teams as they balance personal glory and directing the development of the car in their favour with achieving team goals.”

Watch the latest developer diary below as chief F1 2011 game designer Stephen Hood discusses what he most enjoys about this new co-operative racing mode, with healthy collections of in-game footage included:
