With the launch of Call of Duty Points in Black Ops 3, Treyarch has added the ability to buy extra slots pack; the Extra Slots pack gives players 10 sets of slots in Create-A-Class, expands media storage and showcase storage by more than 3 times the number of slots for Emblems, Paintjobs, Gunsmith Variants, Screenshots, Films, and Custom Games.

In order to acquire the Extra Slots, you can go to Create A Class in multiplayer, and then scroll to the right (R1 on PS4, RB on Xbox One) and the option to buy appears. It costs 300 Call of Duty Points to buy it.
