Rocksteady Studios has released two new DLCs for Batman: Arkham Knight - the 1989 Movie Batmobile and the Bat Family Pack Skin Pack. The first introduces the skins for Batman and the Batmobile, inspired by the 1989 film directed by Tim Burton, along with specific race tracks. Although the skin can be used in any game mode, this version of the Batmobile can only be used in the race tracks, since it does not support the combat mode.
As for the Bat Family Skin Pack, it introduces new suits for Batman, Robin, Nightwing and Catwoman. The two packages are included in the Season Pass, but can be purchased individually. Warner also left some hints for the September update, highlighting the Tumblr, the version of the Batmobile used in Christopher Nolan's trilogy.
You can watch the new trailer bellow (beware of story spoilers!), which includes a sample of the 1989 Movie Batmobile Pack and a teaser for the Tumbler.
