The Mac version of the game, "LEGO Batman 2: DC Super Heroes", was released last year. Like other iOS versions of LEGO games, the game has many of the same features of the Mac version but includes two iOS control styles in "Classic" and "Touch Screen."
This also marks the first time a LEGO game on an iOS device has featured voice acting. Previously, LEGO games for the platform used pantomiming characters to express story elements.
Our sister-site TouchArcade has an overview of the gameplay:
You'll run around doing 3D platforming and light puzzle solving, all the while beating up on both bad guys and objects and then collecting the sweet, sweet Lego studs that are left behind, which are then used to buy different characters and other goodies. Lego Batman: DC Super Heroesboasts an 80 character roster, and not surprisingly it looks like you can buy studs as IAP if you desire.
LEGO Batman: DC Super Heroes is a universal app available in the App Store for $4.99. [Direct Link]
