GamesIndustry.biz reports Martin Walfiz has parted ways with Massive Entertainment (Ground Control, World in Conflict), the Swedish development studio he founded, a move that is surely related to Ubisoft's acquisition of Massive late last year. There are no real details, just this quote from Ubisoft: "Ubisoft is saddened by the recent departure of Martin Walfiz from Massive Entertainment and we wish him all the best in his future projects."
