In what has become a common refrain over the past month, four more former Infinity Ward employees have joined former studio heads Jason West and Vince Zampella at Respawn Entertainment.

G4 is reporting that Preston Glenn, Sean Slayback, Chad Grenier and Zied Rieke have all joined the startup. Grenier and Rieke are senior and lead designers respectively, while Glenn is a level designer and Slayback is a game designer.

The defections bring the total number of employees who have made the jump to 16. With Infinity Ward continuing to bleed employees, Janco Partners analyst Mike Hickey speculated that the studio will be "essentially closed" after the next map pack.
