Why Microsoft Paid So Much for Call of Duty (It Started with a 2019 Game)

Microsoft spent $68.7 billion to buy Activision Blizzard in 2022, making it one of the biggest technology deals ever. Call of Duty — the popular shooting game franchise — was a major reason why. The path to that purchase began with a single game: Call of Duty: Modern Warfare, which came out on October 25, 2019, according to Activision's official announcements.

Modern Warfare was not just a new version of an old game. It was a complete restart of the franchise. The last Modern Warfare game had come out in 2011. By 2019, the series had become stale. Players were tired of fighting in made-up future worlds with laser weapons and flying soldiers. Modern Warfare brought them back to a grounded, realistic military setting that felt urgent and current.

A New Foundation from the Ground Up

To pull off this restart, the developers at Infinity Ward built an entirely new engine — the underlying technology that makes the game run. Think of an engine like the foundation of a building. The old Call of Duty games had been built on the same foundation for over a decade. That foundation was wearing out and could not handle what modern games needed to do.

The new engine allowed for more realistic lighting, better physics, and bigger multiplayer maps than before. It also let players fight on maps with multiple floors and more complicated layouts — a shift away from the simple three-corridor designs older games had used.

Timing and Competition

Call of Duty released once a year, like clockwork. Three different studios at Activision took turns developing each new game, which meant there was always one ready when the previous year's version got old. Modern Warfare arrived in October 2019, right on schedule.

At that moment, the company faced real pressure. Epic Games' Fortnite had stolen millions of players by inventing the "battle royale" mode — a game where 100 players fight on a shrinking map until one survives. A new game called Apex Legends had just launched with the same battle royale idea and was getting a lot of attention. Activision needed Modern Warfare to be good enough to win back players.

A Whole New Way to Play Together

Modern Warfare did something important: it let players on PlayStation, Xbox, and PC play together in the same game. That might sound simple, but it was a big technical challenge. Each platform had different controllers, different performance levels, and different anti-cheat systems to catch cheaters. Getting them all to work fairly together required solving problems that most games had avoided until then.

This became the template for how big multiplayer games are made today. Any competitive game that wants a large audience now has to work across multiple platforms.

Why This Matters for Microsoft's Giant Purchase

The broader context here: Modern Warfare was a turning point. It proved that Call of Duty could still be a money-maker in a world where other games were winning. When Microsoft bought Activision Blizzard for $68.7 billion according to Reuters, Call of Duty was the jewel in the crown. Microsoft wanted to own the biggest shooting game franchise in the world and lock it into its own subscription service.

The deal also signals a larger shift happening in the industry. Companies are no longer fighting mainly over who has the best hardware or fastest processor. Instead, they fight over who has the best games and services. Microsoft is betting that owning Call of Duty will push people to sign up for its Game Pass subscription, similar to how Netflix's exclusive shows drive subscriptions.

A Legacy That Shaped What Came After

Modern Warfare's success created the blueprint for the next several Call of Duty games. The engine technology Infinity Ward built was used again and again. More importantly, the game proved that players would come back to Call of Duty if it felt fresh and serious — not cartoonish or dated.

From a technology standpoint, watching this unfold over the past three decades, I've seen this pattern before. Big franchises hit a wall, fall out of favor, and come back only if their makers are willing to start from scratch. Modern Warfare did that. It gave Call of Duty a second life, turned it into the centerpiece of Microsoft's gaming empire, and reshaped the entire industry's approach to cross-platform multiplayer games.
