Activision has today made all four Call of Duty: Black Ops 3 DLC Zombies maps available for separate purchase, for those who want the maps but do not want to buy the entire DLC Packs.
Each of the four maps costs $7.99, and purchasing each map will give you a bonus of 5 vials of Liquid Divinium to help in fighting off the undead.
If you already own the Call of Duty: Black Ops 3 Season Pass or bought any of the four DLC Packs, these are the same maps with the same content. This is just a easier way for players who want some of the maps and not the entire DLC to get access of them.
Each of the maps are available separately on PlayStation 4 and Xbox One. Coming soon to PC.
