How to unlock Regal camo in Modern Warfare Remastered – New MWR Camo

There is now a higher camo to achieve in Modern Warfare Remastered. Call of Duty 4 Modern Warfare originally had Gold as the highest possible camo. 

However, now the Regal camo can be obtained when the player unlocks Gold camo on all weapon classes. The Regal camo is similar to the Royalty camo which features in Advanced Warfare.
