Activision is encouraging people to play and complete the Call of Duty: Modern Warfare III campaign by offering up a variety of bonuses. The company has announced 14 in-game bonuses that players can unlock for completing the game’s 15 missions.
The bonuses, which include things like calling cards, double XP tokens, Operators, and even a weapon blueprint, are unlocked after almost all of the missions. There are 15 missions and 14 rewards, so it seems like only one mission doesn’t offer a reward.

Modern Warfare III’s campaign rewards are available across multiplayer, Zombies, and Warzone, and you don’t need to play the campaign via early access to get them. Everyone is eligible.
