If you have played one of Treyarch's Call of Duty Black Ops games you will know about the Nuketown map, this is one of the franchises defining maps which fans love and even though they are all the same map they slightly change each game. For the latest game Black Ops 3 Nuketown (or Nuk3town as its called in the game) was a preorder bonus much akin to many other high profile games. For most people who didn't preorder the game you didn't get this map with the ability to download, however chances are looking like Playstation 4 owners will soon be able to download the map as early as January.
This is of course according to the Playstation Store which lists Nuketown for a January release, for those who are interested in the map this is good news. However at this time we only know about the Playstation 4 version of Nuketown with no official date being listed for the Xbox One side at this time.
According to the store the map should be available for those who could not get it on January 26th, this of course is yet to be confirmed by Activision but I would say it is pretty likely.
