Call of Duty developer Infinity Ward, and parent company Activision, have both signed a new employee.

Brian Horton, game director of Rise of the Tomb Raider, announced that he would be leaving Crystal Dynamics for a “new adventure”. Horton had been with the company since August 2009.

Brian Horton has updated his Twitter bio to his new title, Art Director for Infinity Ward.

Although Infinity Ward hasn’t signed Darrell Gallagher directly, he is now working for Activision. Gallagher was part of Square Enix’s team for 10 years, leaving at the end of 2015. Gallagher has signed on as Senior Vice President and Head of Development.
