IDW Publishing has released numerous Transformers film tie-in comics over the last couple of years, but none thus far above average. But the second of their Revenge of the Fallen prequel series stands in, pun intended, defiance of that trend.

The four-issue “Alliance” mini-series bridges the gap between IDW’s own “The Reign of Starscream” series and Paramount/Dreamworks’ “Transformers Revenge of the Fallen” feature film. But that’s the problem, the story functions merely as a bridging piece and offers nothing of deeper substance.

If, while watching the end credits of Transformers (2007) and waiting for your hearing to return, you saw Starscream blasting off into space and wondered just what happened next, then the answer is to be found within the pages of “The Reign of Starscream”.

Never mind all this hype about Transformers on the big screen, because Transformers comes to the touchscreen. IDW has published the first issue of its official “Revenge of the Fallen” tie-in prequel comic in digital format on the iTunes App Store.
