Rainbow Six: Patriots, the one again, off again shooter from Ubisoft's collective of studios could still be in development, as suggested by an employee's CV.
As spotted by industry sleuth Superannuation, the LinkedIn CV of Ubisoft Montreal's Team Lead Event Scripter Thomas Begne states that he started work on a project simply called 'Rainbow Six' in April 2014.
This is, of course, highly ambiguous and not a measure of anything, so please do treat this as rumour for now.
Meanwhile, we've asked our local Ubisoft rep for comment. Stay tuned.
