COD: Modern Warfare Remastered introduces supply drops
The new Call of Duty Modern Warfare Remastered update not only added new maps to the game but also introduced micro-transactions in the form of supply drops. Supply drops aren’t new to the Call of Duty franchise being introduced back in Advanced Warfare.
Supply drops give you access to weapon camo, character skins and sights to give it more personalisation. Supply drops can be bought using depot points which can be earnt in-game or through real money.
Also introduced to Modern Warfare Remastered are female character models in multiplayer which is pretty cool considering the original 2007 version did not feature this.
