It seems that Infinity Ward is on on a slow decline as it was just announced that 2 additional longtime employees have departed the studio. First up is Jon Shiring, a programmer over at Infinity Ward who has been with them for almost 6 years. Additionally, Mackey McCandlish, a designer who has been with Infinity Ward for 8 years has left.
There’s no telling why they left but I’d say it has something to do with Activision being, well, Activision. I wonder if they will join Respawn Entertainment? Let’s hope so.
