One of the hallmarks of the Call Of Duty series is that these first-person shooter games’ annual installments usually only makes incremental changes, not big ones. Not since 2007’s Call Of Duty 4: Modern Warfare, anyway. And while that’s certainly true of Call Of Duty: Modern Warfare II (PlayStation 5, PlayStation 4, Xbox Series X / S, Xbox One, PC), some of the changes they have made in this installment make things rather interesting.
