Three prominent staffers have left Amazon Game Studios - including one of its most high-profile hires, Far Cry 2 designer Clint Hocking.

Hocking joined Amazon to head up its studio in early 2014. He was previously lead designer on Splinter Cell: Chaos Theory and Far Cry 2 at Ubisoft, and had worked at Valve and LucasArts.

Also, Amazon's director of narrative design Eric Nylund, who previously worked on Halo games at Microsoft, has left. As has Jonathan Hamel, formerly of Tomb Raider studio Crystal Dynamics.

Portal creator Kim Swift, who was hired at the same time as Hocking, remains at the firm.

So far, Amazon has mostly published games for other studios like Human Head's Lost Within, WayForward's Til Morning's Light, and Frontier's Tales from Deep Space. Its last internal game was Fire Tablet exclusive, The Unmaking.
