Transformers DS preview at NintendoWorldReport.

"The Nintendo DS adaptation of the Transformers movie is quite different from the console games. For one thing, there are two different versions of the DS game – one for Autobots and the other for Decepticons. Each one has different playable characters, a somewhat different story, and one exclusive level. Both versions are open world games with mission-based campaigns, which is a similar game design to the console versions, but this will be one of the first games to attempt such a thing on the DS platform."
