I suited up for a brief go this morning on my iPhone 5, and the app looks to be a mobile adaptation of the combat, albeit in one-on-one scenarios. The controls are simple enough: You tap to punch, put three taps together quickly to pull of a combo, and hold two fingers down to block. There are QTE-like swipes that appear as you put together moves, and you can switch combat stances as you deal with successive goons. Progress along and you can upgrade Batman's skills and stances, as well as unlock Batsuits, some of which are exclusive to the mobile game.
The App Store blurb also notes "cross-platform unlocks" to tempt those planning to reunite with the Dark Knight next week. On that note, check out Arkham Origins' TV commercial after the break for some full-on, hardcore Bruce Wayne staring.
