Marvel has launched a number of innovative apps for its comics and characters IP, as has parent company Disney. Now it’s teamed up with an external developer, Loud Crow Interactive, for the official comic book-app for new movie The Avengers: Iron Man – Mark VII.

It’s billed as an “epic interactive comic book experience through the design logs of super hero Tony Stark”, including a new story, a soundtrack from the Iron Man and Iron Man II films, and all manner of interactivity. The app is free, too – so emphatically a promotional device for the film rather than a revenue stream in its own right.
