Jacob Minkoff, Infinity Ward’s Design Director, has revealed in a new interview with IGN that Call of Duty: Infinite Warfare’s campaign will feature side missions alongside the main story that will provide players with in-game rewards.

“As the captain of the UNSA Retribution, which is the carrier that you command, you can order it to go and engage in different missions in a non-linear order.”

The side missions will offer players in-game rewards and even add, optional more elements to the entire story. These side missions are all optional, and players can still play the entire campaign in the linear order as previous Call of Duty titles.

“We are telling a linear story, but along the way you can choose to attack targets of opportunity, and attacking those targets of opportunity will reward you with various items and progression and loot elements that will help you to accomplish the next main mission that you accept from command,” he added, noting they “will also reveal optional elements of the story.”
