Batman: Arkham City is littered with the Riddler's trophies, challenges and of course, riddles. So what's a Batman to do? You could interrogate Riddler's goons for information, or you could just plunk down three bucks for an iPhone and iPad Map App guide. Choices.
The new Official Map App lets you pick a territory of the Arkham City map, zoom in to view the location of Riddler trophies, and even gives detailed instructions on what to scan to solve the riddles. It's not exactly sporting, and sort of undermines the point of thinking through a riddle, but if you want a shortcut to unlocking Challenge Maps and other bonus content, it's available for $2.99 on iPhone and iPad.
