Game Progress: Game progress in Call of Duty: Modern Warfare is saved to your Activision account, not your platform account. If you choose to link your platform account to another Activision account, your progress will not transfer. Your progress and content are not lost.

Warzone crossplay will enable cross platform that let you play with friends on any platform - PS4, PS5, Xbox and PC, all together in one happy shooty family.

You may be desperate to play Call of Duty Black Ops 4, but if you haven't played the last installment in the shooter franchise you can now pick up Black Ops 3 for free on PlayStation 4. If you're a PS Plus subscriber, you can download the game as one of the PS Plus free games from today.

$59.99 gets you the game. You do need to buy PlayStation Plus to play Call of Duty: Black Ops 4 multiplayer. There is a local area, but you need another player in the same room, or another player from your [online] player list to really play custom games. There is no traditional single player mode.
