It seems that there is at least one hidden challenge in Call of Duty: Modern Warfare Remastered.

On Twitter, Raven Software lead designer Amos Hodge revealed that there is at least one hidden challenge in Call of Duty: Modern Warfare Remastered. In the tweet, he stated: “Every challenge unlocks an item and there is at least one hidden challenge in #MWRemastered.”

It was revealed last month that Modern Warfare Remastered will offer bot options in private matches. It was also revealed that players will have the option to turn off the HUD indication whenever they receive a medal.

Earlier this week, the Activision blog released a number of details that players should know about the newly released Call of Duty: Infinite Warfare. Revealed in the post was the Specialist Mode, which can be unlocked by beating the game on any difficulty. In this mode, there is no health regeneration, and helmets are the only protection from headshots. Beating Specialist Mode will unlock the YOLO Mode, which implements permadeath. Once a player dies, they have to start back at the beginning of the campaign.

Call of Duty: Modern Warfare Remastered is available now of PC, PlayStation 4, and Xbox One. The game comes as a part of the Legacy Edition of Call of Duty: Infinite Warfare.
