• Crime Fighter Challenge Pack #1 - Players should expect to receive six AR challenges intented for Batman, Nightwing, Robin and Catwoman. This downloadable challenge pack will support focused training that will be used in Freeflow Combat as well as Invisible Predator stealth incursion. The Crime Fighter Challenge Pack #1 is scheduled for release on Sept. 1.

Using this type of Batmobile, players can race through two customized tracks.
