Walter Kong has been promoted to senior vice president and head of development for live games and mobile platforms at Blizzard Entertainment. He joined Blizzard in 2011 as senior director for strategic initiatives, left for Epic Games in 2018, and returned in 2020 as an executive producer before becoming general manager for Overwatch. In his new role, he will oversee the strategic direction of Overwatch and other titles like Hearthstone and Diablo Immortal, although Blizzard has stopped developing new content for Warcraft Rumble and reduced staff in that area. Kong expressed gratitude for his opportunities at Blizzard and is committed to fostering a collaborative and growth-oriented environment.
