Call of Duty: Modern Warfare is giving players many challenges and options to get more content and XP rewards by just playing the game. 

A feature in Call of Duty: Modern Warfare to encourage players to get more XP rewards and potential loot rewards is called Daily Challenges. 

Daily Challenges will reset every 24 hours and per Infinity Ward will be different by player to player. There’s no set list of Challenges that will be available to all players at the same time. 

Daily Challenges will let players get bonus XP to help level up your ranks by playing Call of Duty: Modern Warfare.

During our review event in LA last week, we had a set of 3 Daily Challenges, of which two offered XP rewards and one offered both XP reward and a special cosmetic emblem. Infinity Ward says more challenging Daily Challenges will have loot items alongside XP bonuses, while easier ones will just award XP.
