UPDATE 25th Sep 2019: Infinity Ward's narrative director Taylor Kurosaki has responded to complaints over Call of Duty: Modern Warfare's PlayStation 4 timed exclusivity for the Survival mode of Spec Ops, pointing to "decisions that are above all of our pay grades".
Developer Infinity Ward has been caught in the firing line after it was revealed Survival mode is exclusive to PS4 until 1st October 2020.
Deals for content to be used as timed exclusives are usually done by publishers and platform holders, and it's Activision's deal with Sony for Modern Warfare that has sparked the current Call of Duty outcry.
