The Call of Duty XP build of Call of Duty: Modern Warfare Remastered featured medals that sounded exactly the same as the medal sounds in Call of Duty: Advanced Warfare.
Over the past few days, Raven has also announced the sounds for certain weapons are being updated, and the kill feed icons for headshots/melee are being reverted to the original.
