The developers behind the Call of Duty franchise are restless. Yes, the series is the current king of games, routinely topping the end-of-the-year sales charts with only occasional disruptions from Rockstar. It doesn't need to change. It could continue coasting on its success knowing it has an army of fans to gobble up every entry. But like I said, the developers are restless.
The world is changing and games are changing right along with them. When Call of Duty 4: Modern Warfare launched 12 years ago, it set the standard for gameplay and storytelling in military first-person shooters. It continuously upped the ante, doing what it could to shock players with the horrors of war. But as it escalated from "No Russian" to blowing up children, the effects of these moments started to wane. It was horrific for sure, but the real world provided violence more visceral than anything Modern Warfare was attempting. Couple that with gameplay that cared far more about making players a bad-ass soldier than giving any sort of insight into the nature of war and warriors, and you end up with a series that's an immature person's idea of mature.
Modern Warfare, coming to PS4, Xbox One, and PC this October, aims to give a more honest look at war and conflict. Rather than continue as a series that pushes you to shoot anything that moves, this re-imagining of the Modern Warfare concept would rather players know when not to pull the trigger.
