Call of Duty: Modern Warfare is getting a multiplayer Survival Mode which will be exclusive to the PlayStation 4 and will only come to PC (and Xbox One) on 1st October 2020.
Timed exclusive content is always a shame, given that by the time 1st October 2020 rolss by Activision will be selling a brand new Call of Duty game with, one can assume, another yearly timed piece of exclusive content.
This generation's Call of Duty: Modern Warfare will see some interesting developments in multiplayer, where for the first time PC players will be able to crossplay with console players.
