US games giant Activision Blizzard has hired Grant Dixton as its new chief legal officer.

That's according to an 8-K filing with the Securities and Exchange and Commission – spotted by Bloomberg Law – in which the company said that he'd be replacing Chris Walther, who is departing the firm on June 14th. Dixton has spent the last 15 years working at aerospace giant Boeing, where he was most recently an SVP, general counsel and corporate secretary.

Before that he spent three years working at The White House as associate counsel to the President.

Walther, meanwhile, has spent almost 12 years at Activision Blizzard, having joined the company back in 2009.

This is the latest top-level shift at the company, following the games giant promoting Armin Zerza to the role of chief financial officer in March of this year, the same month that former Homeland Security advisor Frances Townsend was hired as EVP for corporate affairs, chief compliance officer and company secretary.

Meanwhile, Johanna Faries has been appointed general manager of the Call of Duty franchise following the departure of Byron Beede.

It emerged recently that Beede has taken a job at Activision Blizzard's rival Electronic Arts heading up that company's own Battlefield franchise.
