Hello this is my guide for this achievement` if you are wanting to know what the new maps are then here the are i took the liberty of going through all maps and then purchaseing the Dlc and seeing what the new ones were so here they are.
FIVE MAPS.
1001 Fights. (Picture of a castle)
End of the line. (picture of a Train)
Hard Days nights.(Pictue of Metal buildings)
Towering infernal. ( Picture of building site with sheep)
Thranno Saw us. (Picture of Dinosaur)
The best way to get the map your looking for is to keep searching a quick ranked match until you get the map your looking for it does not say what map it is but the way to determine what map it is is to look at the picture you can check them by setting up a custom match (non ranked) where it lets you pick a map and then remember the picture for it when you are searching for the ranked game. Basically after that it is up to you to win or boost this whatever.
Hope this helps or at least saves you time.
