Recently Peter Vesti, who is a Battlefront 2 level designer, confirmed that he has made a Crait map for blast! He said that it should be coming out very early in 2018.
I love the Crait galactic assault map in the game, so this should be a great addition to the game.
I have also heard that we should be getting some other small maps for Crait in the upcoming updates. These will hopefully be maps for Heroes vs. Villians and Strike.
Thanks for reading and as always may the force be with you!
