The Swedish Army drafted Patrick Bach in the early 1990s and tried to make a soldier out of him. No such luck. Mr. Bach couldn’t see the point of pretending to protect a country at peace since the Napoleonic wars. The only part he liked was the shooting.

Twenty years later, Mr. Bach commands a high-tech army that is at war all the time. As the creative force behind the Battlefield series of video games, he must make sure that players come back again and again, no matter how often they get whacked. Which, if you are keeping score, is about seven billion times in the last two years.

For months, a development team in Stockholm has been frantically preparing a new version of the game. Played out in desolate cityscapes, on the sea and in the skies, Battlefield 4 is a dream of Armageddon without civilian suffering to make things messy. Already, fans are hailing what one early reviewer called “an insane new level of destructibility.”

Bloody and dramatic as it is, Battlefield 4 is only the opening move of a bigger effort by Mr. Bach and his colleagues at Digital Illusions Creative Entertainment, or DICE, a development studio owned by the Silicon Valley gaming powerhouse Electronic Arts. They are trying to create a new type of military shooting game even as the genre confronts technological, narrative and public relations hurdles. If they fail, video games will be that much closer to extinction.
